1. DEPARTMENT OF PHYSICS

PANJAB UNIVERSITY, CHANDIGARH

The Physics Department at Panjab University, Chandigarh, is one of the most prominent Physics Department among Universities in India. Since it’s re-establishment in Chandigarh in the 1950’s, it has launched nationally pre-eminent and Internationally significant Research programs in the chosen areas of High Energy Physics, Nuclear Physics and Condensed Matter Physics. These programs are in addition to the Undergraduate and Post-Graduate (Honours School) programs in Physics, and Physics and Electronics which have augmented the maximum sanctioned strength of B.Sc (Hons. School) students from some 90 students in the mid-1990’s to over 200 students today, and that of M.Sc. (Hons. School) students from 100 to over 270 today. On top of these, there are 120 Ph.D. Research Scholars. There is also an M. Phil course with 15 students. An underlying service commitment to teach subsidiary courses in Physics to about 200 Undergraduate students from other Science Departments takes the numbers of students using the Physics Department facilities each day to some 800 students and research scholars. Department of Physics is already a significant present or proposed locus of National investment in advanced research facilities in High Energy Physics, Nuclear Physics and Condensed Matter Physics running in the Department for the last half century and ever increasing levels. A balance between the teaching and research performance has been maintained by the faculty members with proven academic and research credentials in Theoretical and/or Experimental Physics.

In view of the burgeoning size and activities of the Department, as a part of the request for XII plan proposal, the Dept. has submitted a request for formation of a linked University Institute of Physics. It may be noted that this proposal is very much in tune with the call of the Hon’ble Prime Minister to double investment in Science and Technology and the acute difficulty in doing soon the basis of green field facilities while ignoring the languishing and increasingly moribund Universities where the bulk of the nations students and faculty are relegated.

The Department has already gone through various stages of recognition since its inception after the Panjab University re-chartered on Oct 1, 1947 after partition. The Physics department moved to present Panjab University campus in 1958. The department had humble beginning in research in Experimental High Energy Particle Physics with the establishment of Nuclear Emulsion Lab. by Prof. B.M. Anand. The Nuclear Physics group got a boost with establishment of Cyclotron Facility by Prof. H.S. Hans. Since then the department has gone through various prestigious funding stages of UGC/DST/DAE for Research and Teaching as mentioned below:

(a) UGC COSIP (College Science Improvement Programme) and ULP (University Leadership Programme) 1977-1983

2

(b) SAP (Special Assistance Programme)1980-1988

(c) COSIST (Committee on Strengthening of Infrastructure in Science and Technology)1984-1991

(d) Center of Advanced Study (CAS) status since1988 Unique feature – CAS in all three major thrust areas of Physics granted :

• High Energy Particle Physics (Expt. & Theory)• Solid State Physics (Expt. & Theory)• Nuclear Physics (Expt. & Theory)

(e) Funded for IV th phase of Centre for Advanced Studies (CAS) in 2009 after successful completion of previous three phases since 1988.

(f) Funding under DST-FIST-I (Funds for Improvement of Science & Technology) Programme (2003-2008) and DST-FIST-II (2009-2013).

As mentioned above, the department has already achieved the standing of a National Institute due to its very active research programmes. In the XII Five Year plan, the department has proposed for its status as University Institute of Physics, which would take this department to new heights in research and teaching programs. It will provide the department sufficient autonomy to make the teaching programmes more research-oriented and facilitate scientific research by providing support at all levels ranging from general administrative matters to infrastructure support. The main strengths and achievements of the established research groups in the Department are given.

In a related development, recognizing the growth of the Department and its pressing space requirements the University has constituted a high level committee to recommend expansion of the Physics Dept. by construction of addition 15000sq ft as demanded by the department in view of its saturation of available space. The UGC-CAS could greatly help the dept. in gathering funding for this vital requirement. Details are given in Chap. 9 of this report.

(A) Experimental High Energy Physics Group

Experimental Particle Physics & Heavy Ion Group:

(i) Experimental Particle Physics GroupSince 1954, the Physics Department, Panjab University group has been actively engaged in the experimental High Energy Physics Research initially using Nuclear Emulsion Technique. Using this technique several Cosmic rays as well as particle accelerator based experiments were performed. Later on in 1975, after TIFR, Panjab University was thE only University to initiate setting up Bubble Chamber Technique facility and using know how from TIFR and Michigan State University, Bubble Chamber projection Systems were developed at CSIO, Chandigarh. Using this facility group participated with CERN on several Bubble Chamber experiments using beam at 780 MeV, 40 GeV K-Beam and 360GeV Proton Beam. Later of its own with having Collaboration of TIFR, Panjab University used Bubble Chamber Facility to participate in Tevatron Neutrino experiment with Fermilab(USA). During late 80’ Group started participating in Frontline International Experiments using Electronics detectors like; Dzero(Tevatron,USA), Belle(KEK, Japan), WA98(CERN), ZEUS (HERA),CMS(CERN),ALICE(CERN),STAR(USA). These Experiments led to the following discoveries: Discovery of TOP Quark (1995) Discovery of CP-violation in B-meson System(2001,2003) Discovery of new particle state with Belle Observation of Quark-Gluon PlasmaFollowing are the details of contribution and participation in various International Collaborative Experiments :

Belle Experiment at KEK (Japan)One of the most mysterious phenomena in the particle physics that remains unresolved is the CP-violation which is considered to be responsible for the baryon-antibaryon asymmetry in our section of universe. Keeping in view the importance of CP-violation effect, two dedicated e^+e^- collider machines (B-factories) have been pursued in the world - one at KEK(Japan) and another at SLAC(USA). The KEK accelerator and Belle detector have been made operational and started data taking in July 1999. The observation of a CP-violating asymmetry in B-meson decays is an important milestone in high energy particle physics by these B-factories. From Panjab University along with students, we have been participating in this Prestigious International Experiment.The Panjab University would continue to participate in Data taking, Physics analysis of the Belle Experiment at KEK B-factory (Japan). The Belle collaboration has already made truly historic achievements in the area of Quark Flavour physics and has become a world leader in this branch of high-energy physics. The experiment would continue to run during next several years and also intend to upgrade the World's Highest Luminosity KEKB accelerator to new Accelerator Super-KEKB and the Belle Detector. During next 10-years group would participate in the Physics analysis with higher statistics which would lead to more and more discovery of new particles and new phenomenon in the field of B-physics including Direct CP-Violation. To summarize we intend to Participate in Data taking with Belle Detector at KEKB factory Physics Analysis for the observation

new B-decay modes Search for Direct CP-Violation in new rare B-decays Detector development and R&D for Silicon Detector for Super-KEKB detector

CMS Experiment at LHC (CERN)

Group is participating in the Compact Muon Solenoid (CMS) experiment at Large Hadron Collider (LHC) at CERN, Switzerland. The LHC is going to be the Highest Energy Accelerator for next 10-15 years and would provide unique opportunity Search of new particles and new physics at TeV scale. The CMS experiment is one of two large general purpose particle physics detectors capable of studying many aspects of proton-proton collisions at Centre of Mass Energy 14TeV. It contains sub-detectors which are designed to measure the energy and momentum of photons, electrons, muons and other particles produced in the collision. At Panjab University along with TIFR, we took complete responsibility of designing, fabrication, testing and installation of one of the sub-detector called Outer Hadron Calorimeter (HO) into the CMS detector.

For this purpose, we got about 900 plastic scintillator tiles grooved at CTR, Ludhaina. These tiles were assembled in the form of detector and tested with Data Acquisition at Panjab University and TIFR. After complete tested and assembly, these have been integrated with the CMS detector. The final tests and commissioning has been carried by the team of Engineers and Scientists from TIFR and Panjab University and detector is ready to be used. During next 10-15 years, these detectors would be used for the data collection at LHC and we need to make sure the smoothing running of our HO detector with some required upgrade. Group members and students are studying various physics aspects like, Higgs Search, SUSY particle Search, B-physics, Top Quark study, QCD study, etc. With the start of LHC in June/July 2008, the group members have participated in data taking with CMS and physics analysis related to various physics aspects-Higgs,B-physics,QCD,etc. The group also developed expertise in setting up Grid Computing infrastructure for unifying with the WLCG (Worldwide LHC Computing Grid) for doing the distributed data analysis. The required computing hardware/software were configured locally to accomplish these tasks of data analyses.

Dzero Experiment at Fermilab (U.S.A)

Group members are participating in Dzero experiment at Fermilab and are part of International Dzero collaboration. EHEP group of P.U has made significant contribution for hardware and software of D0 experiment at Tevatron energy which led to Top Quark Discovery which was one of the milestone for Particle Physics. Currently we are participating in data analysis and physics studies of signal and background for Higgs and top properties. Group also participates in detector shifts as well as online data monitoring shifts.

ZEUS Experiment at DESY (Germany)

Members of HEP group are involved in the ZEUS experiment at DESY, Germany. The experiment is aimed at studying electron (positron)-proton collisions at HERA accelerator which collided 27.5 GeV electron/positron longitudinally polarized beams with proton of energy 460, 575 and 860 GeV. The physics is dominated by the

7

interactions of gluons and probes the structure of proton down to distances 10 -16 cm to confront the Standard Model (SM) of strong and electroweak interactions in search of signals of Physics beyond the SM. Many important physics topics will benefit from data at different center-of-mass energy, such as measuring associated structure function FL , to understand small-x physics, measuring structure functions at higher values of x leading to more precise extractions of parton distribution functions, measurements of cross sections for longitudinally polarized virtual photons to scatter off protons for inclusive and diffractive physics. The results thus obtained will make an important and essential input to LHC physics.

(ii) Heavy Ion Physics Group:

The Chandigarh group is a part of international collaborations, STAR experiment at RHIC(BNL, USA) and ALICE experiment at LHC (CERN, Geneva), to study QCD matter as a function of density and temperature reached during heavy ion collisions at ultra-relativistic energies, i.e. the state of matter existed during the first few microseconds of the big bang. Recent results of four experiments, BRAHMS, PHENIX, PHOBOS and STAR, at RHIC have shown the formation of extremely high energy density system in Au+Au collision, whose description in terms of simple hadronic degrees of freedom is inappropriate. Further more, the constituents of this system (quark-gluon plasma) experience a significant level of interaction with each other inside the medium (liquid state). This is considered to be an ideal gas in the theory of QCD. The minibangs at LHC will briefly reach several times the energy density and the temperature that reached in RHIC collisions. This will be interesting to see if the liquid like behavior witnessed at RHIC will persist at the higher temperature and densities encountered at the LHC.

The research work at Chandigarh is related with the development fabrication and testing of the Photon Multiplicity Detector (PMD), read-out chip testing, installation and calibration of PMD, maintenance and data taking during the runtime and in the analysis of data to extract following signals of QGP:

i) Determination of reaction plane and collective flow.ii) Fluctuations in the number of produced particles.iii) Disoriented chiral condensates.In addition to the above experiments, the group is intended to participate in

the Compressed Baryonic Matter (CBM) experiment at Darmstadt (Germany) also. The experiment offers the possibility to discover the first order deconfinement phase transition and the critical end point of the QCD phase diagram expected to exist at high net baryon densities.

Participation in Neutrino Physics Program using INO - India-based Neutrino Observatory

During next 10-15-years, several faculty members of the department would participate in the Neutrino Physics Program of the Country. In this regard, jointly Department of Atomic Energy and Department of Science and Technology have proposed a 1300 Crore Rupee Mega science project near Mysore. This experiment would require big 2mX2m

8

more than 12000 Resistive Plate Chamber detectors and also, huge efforts on Neutrino Physics and detector simulation. Panjab University group members have started working on the Detector development, theoretical aspect of Neutrino physics and physics simulations.

Detector Development Facility:Panjab University group established the various modern detector development facilities during the course of these years starting from the collaboration with the DZERO detector at Fermilab to the latest on-going CMS detector at CERN. These facilities include:

Scintillator Based DetectorTo provide the coverage to the DZERO detector from the cosmic muons (forming one of the background signals) and vetoing them, the local HEP group started the R & D work and setup the scintillator based detectors. A prototype was developed which was approved by the collaboration. This whole activity allowed us to develop local zigs for testing the WLS (wave length shifting) fibers for attenuation studies, bonding-coupling of fibers with the light guide and shaping the scintillators for maximum light gathering. The whole setup was CAMAC controlled.

This expertise with the scintillators led to the participation in the CMS Outer Hadronic detector. Thousands of scintillator based detectors were cut/polished/assembled and fabricated with embedded optical fibers with the help from the Central Tool Room, Ludhiana. These were all tested for quality checks locally and where shipped to CERN for installation in the CMS detector.

Gaseous Based Detectors: Under these category of detectors, the group took the responsibility along with BARC, Mumbai to set-up the lab for assembly and testing of Resistive Plate Chambers(RPC) for Muon Detector upgrade. The overall work included: Fabrication and testing in India and then testing, Installation and Commissioning of Indian RPC at CERN with CMS Detector. For this work a new gaseous detector development lab was setup in the department with 4 channel automatic gas mixing and distribution system. The CAMAC based DAQ is being upgraded with the VME based system. Since the group is involved in the INO-ICAL (India based Neutrino Observatory-Iron Calorimeter) experiment which also uses RPCs as the active medium, it was obvious to use the existing facilities for the detector development work for the INO-ICAL. The RPCs used in INO are glass based where as the ones used in CMS are Bakelite based. The group has gained expertise in all the aspects of RPC fabrication, testing (using the cosmic test stand), scintillator paddles/telescope assembly and testing of its response, for both the glass as well as Bakelite.

Projects handled by the HEP Group(Since 1999 till date)

Number of Projects: 8 (funded by DST, DAE-BRNS)

Total Amount of Projects: ~ Rs. 12.5 Crores

Project Proposals Approved (on-going/future collaboration)

The group has joined the Fermilab based neutrino program and has put forward a proposal to participate in the detector building for the Near detector as part of the Long-baseline neutrino experiment proposed by Fermilab.

Other than National Research Institutes, Panjab University has been a major centre being heavily supported by DST and DAE to have active participation in prestigious LHC(CERN) program. Govt. of India has placed the LHC program under Mega Project programe as India has Been recognized as Assosiate Member state of CERN and being considered as member state. The very active participation of this University in this Mega Project program has National interest.

A2. Theoretical High Energy Particle Group

Over the last 15 years both in collaboration with an International group based at the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy and independently Prof. C.S. Aulakh and his students have developed Left Right Supersymmetric models and the the Minimal Supersymmetric SO(10) Grand Unified Theory in a sustained way that has brought these theories to the point where these theories are now in active confrontation with the lates data from the LHC, Dark Matter experiments as well as contributing a testable locus for Lepto-Baryogenesis and Inflationary Cosmology. His work is well recognized by over 1800 citations in the International literature and has resulted in a number of invitations to speak at International Conferences, and direct national (SERC-THEP) and international (ICTP-Summer School in Particle Physics). The theory group has also established a High Performance Computation Centre with Tera-flop supercomputation facilities on a 80 node cluster. These facilities are expressly set up to be of use in the research program of the Theoretical High Energy Physics, Nuclear Physics and Condensed Matter Physics Groups which are already using them intensively. The HEP theory group has made important contributions which are well recognized at the national and international level. Some of the well recognized contributions of the group concerns: (i) Formulation & analysis of consistent Minimal Super-symmetric models of the corresponding Grand Unified Theories, (ii) Texture specific mass matrices and CP violation, (iii) Proton Spin Crisis(iv) Study of existence and the stability of solitonic solutions of non-linear evolution equations. The group proposes to carry out the following activities in the coming year/s.

a) Minimal Supersymmetric Grand Unified Theory:

In the last 7 years the generic class of left-right Supersymmetric Unified models was studied. This study together with Neutrino mass data led us to revive an SO (10) GUT model proposed by us in 1982 as the Minimal Supersymmetric GUT (MSGUT). This GUT is now known to be the minimal GUT compatible with all experimental data and is a focus of intense investigation by at least 5 groups worldwide. We developed a new method for analysing the group theory of SO(10) which enables us to calculate all group theoretic coefficients required. We have already calculated the complete spectrum and couplings at the GUT scale and used them to calculate the threshold corrections to the gauge couplings ab initio (for the first time in any GUT). We have also proposed a new scenario of Asymptotically strong unification based on this type of GUT.

In the coming year/s, we will further deepen our studies of the MSGUT and investigate the fermion spectra, GUT scale dynamical symmetry breaking, renormalization group fixed points and corrections, baryon decay and a host of other phenomenological issues that come into sharp focus once one has available the complete spectra and couplings of this MSGUT.

11

(b) Phenomenological Fermion Mass Matrices & CP Violation:

We have been carrying out intensive studies in the field of fermion mixings, CP violation and fermion mass matrices. In order to understand the quark mixing phenomenon at more fundamental level, texture specific mass matrices have been formulated at phenomenological level. Mass matrices based on discrete symmetry have also been studied with good results for the rare decays. Fermion flavour mixings, neutrino oscillations, neutrino mass matrices and CP violation in the leptonic sector continues to be the thrust areas at present. In the coming years, we plan to investigate intensively the possibility to find CP violation in the electronic sector and viable set of Fermion Mass matrices which are in agreement with the quark mixing and neutrino oscillation phenomena.

(c) Proton Spin Crisis:

We are also investigating the ‘proton spin crisis’ within chiral quark model with configuration mixings generated by gluon exchange. In the next two three years, we plan to investigate the gluon contribution to the spin angular momentum of the nucleon in the context of Chiral Constituent Quark Model.

(d) Nonlinear Evolution Equations of Physics

During the last few years, we studied the existence and the stability of Solitary Wave like solutions for various Nonlinear Evolution Equations of Physics interest. We find exact solutions to the nonlinear Schrödinger equation NLSE in the presence of self-steepening and a self-frequency shift. These include periodic solutions and localized solutions of dark-bright type which can be chiral, the chirality being controlled by the sign of the self-steepening term. A form of self-phase modulation that can be tuned by higher-order nonlinearities as well as by the initial conditions, distinct from the nonlinear Schrödinger equation, characterizes these solutions. In certain nontrivial parameter domains, solutions are found to satisfy the linear Schrödinger equation, indicating the possibility of linear superposition in this nonlinear system. Dark and bright solitons exist in both the anomalous and normal dispersion regimes, and a duality between the dark-bright type of solution and kinematics higher-order chirping is also seen. Localized kink solutions similar to NLSE solitons, but with very different self-phase-modulation, are identified.

The sol–gel system which is known, experimentally, to exhibit a power law decay of stress autocorrelation function has been studied theoretically. A second-order nonlinear differential equation obtained from Mori's integro-differential equation is derived which provides the algebraic decay of a time correlation function. Involved parameters in the expression obtained are related to exact properties of the corresponding correlation function. The algebraic model has been applied to Lennard-Jones and sol–gel systems. The model shows the behavior of viscosity as has been observed in computer simulation and theoretical studies. The expression obtained for the viscosity predicts a logarithmic divergence at a critical value of the parameter in agreement with the prediction of other theories.

12

For the first time, we find the complex solitons for a quasi-one-dimensional Bose–Einstein condensate with two- and three-body interactions. These localized solutions are characterized by a power law behavior.

The dynamic structure factor S(q, ω) of a harmonically trapped Bose gas has been calculated well above the Bose-Einstein condensation temperature by treating the gas cloud as a canonical ensemble of non-interacting classical particles. The static structure factor is found to vanish s8 q 2 in the long-wavelength limit. We also incorporate a relaxation mechanism phenomenological by including a stochastic friction force to study S(q, ω). A significant temperature dependence of the density fluctuation spectra is found. The Debye-Waller factor has been calculated for the trapped thermal cloud as a function of q and the number N of atoms. A substantial difference is found for small- and large-N clouds.

We studied the nonlinear dynamics of DNA, for longitudinal and transverse motions, in the framework of the microscopic model of Peyrard and Bishop. The coupled nonlinear partial differential equations for dynamics of DNA model, which consists of two long elastic homogeneous strands connected with each other by an elastic membrane, have been solved for solitary wave solution which is further generalized using Riccati parameterized factorization method.

We demonstrated that the competing cubic-quintic nonlinearity induces propagating soliton like dark (bright) solitons and double-kink solitons in the nonlinear Schrödinger equation with self-steepening and self-frequency shift. Parameter domains are delineated in which these optical solitons exist. Also, fractional-transform solitons are explored for this model. It is shown that the nonlinear chirp associated with each of these optical pulses is directly proportional to the intensity of the wave and saturates at some finite value as the retarded time approaches its asymptotic value. We further show that the amplitude of the chirping can be controlled by varying the self-steepening term and self-frequency shift.

Keeping in view the importance of dynamical invariants, attempts have been made to investigate complex invariants for two-dimensional Hamiltonian systems within the framework of the extended complex phase space approach. The rationalization method has been used to derive an invariant of a general non Hermitian quartic potential. Invariants for three specific potentials are also obtained from the general result.

During the last few years, various aspects of supersymmetric quantum mechanics and the application of this formalism to various physical situations have been studied. Some of the applications are in the area of information theory, in rearranging the information entropy in a given system, Nonlinear Physics, Atomic Physics and Particle Physics. We use a fractional transformation to connect traveling wave solutions of the nonlinear Schrödinger equation, phase-locked with a source, to the elliptic equations. Bright and dark solitons are obtained in the suitable range of parameter values.

13

(e) Noncommutative spaces and deformed symmetriesAlthough it has a longer history, the idea that configuration-space coordinates may not commute has arisen recently from string theory. Noncommuting spatial coordinates and fields can be realised in actual physical situations. Therefore, many physicists have investigated what follows just from the idea that coordinates are operators that do not commute. Noncommutative field theories have many novel features. We studied the general deformed conformal-Poincare (Galilean) symmetries consistent with relativistic (nonrelativistic) canonical noncommutative spaces. In either case, we obtained deformed generators, containing arbitrary free parameters, which close to yield new algebraic structures. We showed that a particular choice of these parameters reproduces the undeformed algebra. We also studied the deformed conformal-Poincare symmetries consistent with the Snyder-de Sitter space. A relativistic particle model invariant under these deformed symmetries was given. This model was used to provide a gauge independent derivation of the Snyder-de Sitter algebra. Our results were valid in the leading order in the parameters appearing in the model.

A3. Theoretical AstrophysicsWe have recently started working on the galactic chemical abundance evolution

(GCE). The idea is to understand the complete galactic elemental (isotopic) evolution of our galaxy and probably other galaxies. There has been revolutionary development in the stellar nucleosynthesic theories in almost all the stellar evolutionary models. As a result the GCE models could be made much more efficient now. We have been recently working on some of the aspects of GCE models and hopefully will be able to develop my own model. We will continue to work in GCE models for our galaxy and probably other galaxies. In addition, we would like to initiate some work in the laboratory simulation of irradiation of grains by energetic particles to study the production of short-lived nuclides that are found to be present in the early solar system. The group has been working on the theoretical studies related with the origin and the early evolution of the solar system. In this regard, the thermal models related with the early evolution of planetesimals in the early solar system have been developed. This includes the planetary bodies that underwent large scale planetary scale melting and differentiation. The studies include the thermal evolution of icy planetesimals and trans-Neptunian objects. Further, the work is going on for the processes that triggered the formation of the solar system and planetary bodies. The group has extensive cordial, professional relationship with other Institutions through collaborations and visits. The faculty participates in International / national workshops, seminars and conferences and invites visitors under TPSC programme. Participation in Indian Neutrino Initiative (INO), Associateship at ICTP, Visiting Scientist position at IUCAA, DAAD fellowship are some of the honors the group received recently. With this expertise, the group is confident in holding Winter /Summer schools and take up long term collaborative research projects.

(B). Nuclear Physics

Experimental Activities

In House Facilities:

B1. Chandigarh Variable Energy Cyclotron:

Current activities:

Chandigarh Variable Energy Cyclotron is an unique facility amongst the Universities in India. It has been functioning satisfactorily since last many years. This machine has been mainly used to produce 3.0 MeV protons in the last few years and is being used as a regional facility for PIXE, PIGE and polymer irradiation experiments. A new beam line (zero degree) for general purpose experiments is under progress.

(a) PIXE and PIGE Programme:

The low-energy proton beam (~ 3 MeV) is very much suitable for elemental analysis using PIXE and PIGE techniques. At present, Cyclotron is being used effectively for determination of trace elements in Archaeological, bio-medical sciences, Forensic science, aerosol samples etc. Our next aim is to make use of PIGE and RBS facilities along with PIXE for elemental analysis for a variety of samples from various fields. PIGE facility will be used for the detection of light elements such as Li, B, F, Na. Mg, Al, Si and P for which PIXE technique is not suitable. The main thrust of PIGE program will be the elemental analysis of Boron in biological samples, Fluoride in water samples, detection of Al and Si in aerosol samples. PIXE and PIGE techniques will also be employed to the study of elemental constituents of some traditional medicinal plants generally used in curing many diseases and in commonly edible vegetables of medicinal and pharmacological importance. RBS facilities will be used for elemental analysis and depth profiling of the thin films. This programme will be continued for next five years.

(b) Irradiation Work:

The Studies on the effect of low energy (2 to 3) MeV proton beam irradiation on polypropylene (PP), polyethylene terephthalate (PET), polyimide (PI), ethyle vinyl acetate (EVA), polycarbonate (PC) and blended PVC/PET have been investigated at different fluences. Now the focus on polymer nano composites films have been planned for future work. Polymeric films will be synthesized by the dispersion of different concentration of nanoparticles in the polymer matrix using sol gel technique. This work is being done in collaboration with M S University of Baroda, Vadodara. It is planned to strengthen collaboration with other Indian universities for PIXE/PIGE and irradiation experiments in the cyclotron lab.

It is planned to Establish an experimental set up for the (p,γ) and (α,γ) reactions at the Cyclotron of the Department. It is planned to set up neutron activation using proton beam from the cyclotron. Recently, old power supplies of the cyclotron magnet systems were replaced by solid state power supply, by the funding from the departmental CAS

15

programme and a DST project for the regional PIXE programme. At present this is the only accelerator in the country available for low energy proton and alpha beam in the above energy range. We propose to upgrade the existing experimental set up and start a programme for measuring (p,γ) and (α,γ) reaction cross sections which has a direct relevance for nuclear astrophysics and nuclear data. This programme will be use full as a training ground for students of M.Sc., Ph.D. and post-M.Sc. course in accelerator physics of the department, besides its nuclear physics importance. The group efforts for next five years will also be useful for the proposed 5 MV accelerator of the Panjab University. We will need a new HPGe detector and we will also explore to repair the old HPGe detector for measuring life time of the astrophysically important nuclei using DSAM technique.

B2. Establishment of a New 5 MV Electrostatic Accelerator:

In the next five years it is planned to concentrate on a major proposal for 5 MV Tandetron accelerator. The proposal is already defended before the Expert Committee of the DST, Govt. of India. In the next new few months we are expecting final decision from DST. The cost estimate has been projected to be Rs.60 Crores for the main machine, beam lines and some major experimental apparatus. The recurring expenditure will be about 2 Crores which include the salary of the staff, running cost of the machine and arrangement for carrying out the research programme. The facilities will also be extended to other universities and institutes in the country. Planned research programs using 5 MV Tandetron facility are (i) Cluster Physics, (ii)Neutron generation, (iii)Accelerator Mass Spectrometry, (iv) Material modification, and (v) Characterization using Analytical techniques : RBS, PIXE, PIGE, ERDA, NRA, Micro-beam facility and a time-of-flight set-up for heavy ion RBS, Masked ion beam lithography (vi) Nuclear Astrophysics (vii) PAC Experiments. It will also be used for production of radioisotopes for medical/industrial uses – New radioactive probes for PAC studies, PET sources, Positron sources for positron annihilation investigations and radio-active sources for commercial values. In addition, beam will also be given for detector testing facility – for International collaborations and Radiation damage testing of silicon detectors.

B3. Activities at National/ International Level:

Nuclear Structure at High Spins:

The group has been investigating the high spin states in the nuclei populated through fusion-evaporation reactions using heavy-ion beams from pelletron accelerators at the IUAC and TIFR accelerator facilities. Reactions have been investigated through in-beam -ray spectroscopic techniques using the Clover detector spectrometers INGA for gamma-spectroscopy studies. The following investigations have been carried out during the recent past:

(a) Excited states in the 99Pd nucleus populated in the 75As (28Si, p3n) fusion-evaporation reaction at Elab = 120 MeV have been investigated through in-beam -ray spectroscopic techniques using an array of Compton suppressed clover detectors. The level scheme is established up to excitation energy ~11.5 MeV and spin ~ 25ħ with the addition of about 60 new transitions. The level structures observed in 99Pd have been interpreted in the framework of a microscopic theory based on the deformed Hartree-Fock and angular momentum projection techniques. Band structures at lower spins are based on the low -Ω

16

νg7/2 and vd5/2 orbitals, and those at higher spins are reproduced for the π(g9/2)5 Ä π(g7/2) Ä ν(g7/2)2Ä ν(h11/2)2 Ä ν(g9/2)−1 and π(g9/2)6 Ä ν(g9/2)10 Ä ν(g7/2)2 Ä ν(h11/2) configurations. The octupole correlations in 99Pd have been inferred from new interband E1 transitions linking the D I = 1 states of the bands based on the νh11/2 and νd5/2 orbitals (l = 3, j = 3, and D π = −1) with the deduced B(E1) values ~ 10−6 W.u.

(b) High spin states in neutron-deficient 106,107In were investigated using 78Se (32S, pxn) reaction at 125 MeV. The de-excitations were studied using in-beam -ray spectroscopic techniques involving the Compton-suppressed clover detector array. The level schemes are extended up to 7 MeV of excitation energy and spin ~ 22 ħ. In 106In, the negative parity states constituting four dipole bands have been observed. The positive parity states mainly exhibit single-particle excitations. Projected deformed Hartree-Fock calculations were carried out in 106,107In to understand the configurations of different bands in this nucleus. Various bands are reproduced in band mixing calculations with the configurations involving high-Ω πg9/2 and νd5/2 orbits, and low-Ω πg7/2, νg7/2 and νh11/2

orbits.

(c) High spin states in 112In were investigated using the 100Mo(16O, p3n) reaction at 80 MeV. The excited level has been observed up to ~ 6 MeV excitation energy and spin ~20ħ with the level scheme showing three dipole bands. Polarization and lifetime measurements were carried out for the dipole bands. Tilted axis cranking model calculations were performed for different quasiparticle configurations of this doubly odd nucleus. Comparison of the calculations of the model with the B(M1) transition strengths of the positive- and negative-parity bands firmly established their configurations.

(d) Excited states in 131Cs were investigated through in-beam -ray spectroscopic techniques following its population in the 124Sn(11B, 4n) fusion-evaporation reaction at a beam energy of 46 MeV. The previously known level scheme has been substantially extended up to ~9 MeV excitation energy and 49/2ħ spin with the addition of seven new band structures. The present level scheme consisting of 15 bands exhibits a variety of collective features in this nucleus at intermediate spin. The excitation energies of the observed levels in different bands and the corresponding ratios of transition strengths, i.e., B(M1)/B(E2), have been compared with the results of projected deformed Hartree-Fock calculations based on various quasiparticle configurations. A strongly coupled band has been reassigned a high-K three-quasiparticle πh11/2 Ä νh11/2 Ä νd3/2 configuration based on the properties of this band and that of its new coupled side band. The configurations of these bands are also discussed in the framework of tilted-axis cranking model calculations and the systematics of the odd-A Cs isotopes. Additional three energetically closely placed coupled bands have been assigned different unpaired three-quasiparticle configurations. -vibrational bands coupled to the πh11/2 and πg7/2 single-particle configurations have been reported in this nucleus. Observation of new E1 transitions linking the opposite-parity πh11/2 and πd5/2 bands provides fingerprints of possible octupole correlations.

(e) A bandlike structure, based on the πh11/2Äνh11/2 configuration, has been identified for the first time in 134Cs in a gamma-ray spectroscopic study using fusion evaporation reactions. The nature of this band in 134Cs has been found to be distinctly different than the nearly degenerate doublet rotational band structures, observed in the lighter Cs

17

isotopes for the same configuration. Both the total Routhian surface and the tilted axis cranking calculations were performed to understand the experimental observations. The present results suggest that the N = 77 defines the border of the deformed structure in the A ~130 region while approaching N = 82.

(f) The 122Sn(11B,4n) fusion-evaporation reaction at Elab=60 MeV was used to populate excited states in 129Cs, and the deexcitations were investigated using in-beam γ-ray spectroscopic techniques. The level scheme of 129Cs is established up to ~8MeV excitation energy and 47/2ħ spin. The observed band structures are interpreted for their configurations in the framework of cranking model calculations and systematic of the neighboring 55Cs isotopes. A negative-parity DI=1 coupled band has been assigned the h11/2Ä(νh11/2)2 configuration as solution of the tilted-axis cranking, which coexists with the πh11/2 yrast band resulting from the principal-axis cranking. A new band has been identified as a γ-vibrational band built on the πh11/2 orbital. A pair of strongly coupled positive-parity bands exhibiting similar features have been assigned different unpaired three-quasi-particle configurations involving the h11/2Äνh11/2 component. The previously identified unfavored signature partners of the πd5/2 and πg7/2 bands are reassigned as γ vibrations of the core coupled to the πg7/2 single-particle configuration, and the favored signature of the πd5/2 band, respectively. (g) We carried out the experiment using INGA to study the high spin structure in 130,131Ba using 13C + 122Sn at 65 MeV. Preliminary results have been presented in DAE symposium and final results are being prepared to send for publication in some referred journal.

(h) We have proposed the 28Si + 116Cd reaction at 115 MeV to study the high spin structure in 140Pm and 140Sm. This experiment will be carried out at TIFR, Mumbai using INGA in phase –II run.In the future experiments, it is planned to use HYRA for recoil tagging of heavy nuclei, and the ancillary equipments - charged particle ball. Active participation of the group will be there in setting up of the world class facility along with the other ancillary equipments at IUAC. Life time measurements of excited nuclei will be continued through DSAM and RDM techniques.

Nuclear Reaction Dynamics studies at National Accelerator Facilities:

Nuclear reaction dynamics studies will be continued and new experiments will be planned in the National accelerator facilities of Inter University accelerator centre (IUAC), BARC-TIFR accelerator facility and the variable energy cyclotron centre (VECC) at Calcutta. The upgrading of IUAC accelerator with LINAC booster and the new super conducting cyclotron of variable energy cyclotron centre will provide us some unique projectile target combinations in low and medium energy regime for reaction studies.

For the last three years we are engaged in the Neutron multiplicity, Fission cross sections and evaporation residue cross section measurements for the System 16,18O+194,198Pt and 19F + 194,196,198 Pt systems. All the measurements were performed using the Pelletron+Linac accelerator facilities of IUAC New Delhi. For 16,18O+194,198Pt systems the role of N/Z in the neutron multiplicities is established. For 19F + 194,196,198 Pt systems

18

the effect of shell closure in nuclear dissipation is established. The two programmes are complete and Ph.D. students are writing their thesis.

The group will be actively engaged in the fission dynamics studies at IUAC, New Delhi. A neutron array is being established at IUAC in collaboration with Delhi University, Panjab University and Karnataka University and it will come up in next few years. The group has been actively involved in designing this apparatus and proposing experiment the department will be a part of National Neutron Array Collaboration. An experiment using the LINAC beam of IUAC using a 16 neutron detector array was performed to understand the fission dynamics of the heavy nuclei. New experiments are already planned. New experiments for the measurements of spin distribution of medium mass system and Fusion barrier distribution for heavy nuclei is planned and approved by IUAC , accelerator user Committee. Charged particle spectrum for 32S+45Sc and 28Si+45Sc is analyzed. Nuclear Level density for medium mass nuclei in the mass region A=5-80 are extracted from the Alpha particle spectra and systematic study was undertaken. The group has been actively involved in designing and setting up of National Neutron Array at IUAC. An experiment using the LINAC beam of IUAC using a 16 neutron detector array was performed to understand the fission dynamics of the heavy nuclei. Fusion barrier distribution studies through quasi-elastic scattering methods for heavy Nuclei will be performed at IUAC accelerator facilities. The experiments have also been proposed to study the precission and postscission charged particles emission in heavy ion induced reactions at IUAC, New Delhi. Light charged particles spectra will be measured in coincidence with fission fragments and the fission time scales will be extracted using the charged multiplicities. A Project has been sanctioned by IUAC to perform these experiments.

Nuclear physics groups plan to continue with Nuclear Structure, static nuclear electromagnetic moment, Nuclear reaction dynamics studies in the new experiments using National accelerator facilities. The upgrading of IUAC accelerator with LINAC booster and the new super conducting cyclotron of variable energy cyclotron centre will provide us some unique projectile target combinations in low and medium energy regime for reaction studies. New generation gas filled recoil separator (HYRA) at IUAC will give us ample opportunities to study fusion dynamics and gamma ray spectroscopy of heavy system. The group also plans to upgrade PAD facilities involving BaF2 and LaBr3

scintillators at IUAC.

The planned new generation gas filled recoil separator (HYRA) at NSC will give us some opportunities to study fusion dynamics of heavy system. Once it comes up fusion experiments will be proposed for this facility.

B4. International Facilities:

Besides using the national accelerator facilities and the activities in house facilities the group is planning to start renew collaboration and active contacts with the international facilities like GSI at Germany, LNL at Italy and Argon National Lab in USA. The group

19

is planning to join in the GSI future accelerator (FAIR) Collaboration. Faculty members will be involved in planning of the experiments and apparatus for this new FAIR Collaboration.

B5. X-ray Fluorescence Laboratory:

Photon-atom interaction and subsequent processes near the electron binding energies and applications:

The laboratory is equipped with X-ray tube based intense photon source, 241Am and 55Fe radioisotope based photon sources and Low energy Ge detector, Si(Li) detector and recently procured Peltier-cooled detector. Peltier cooled X-ray fluorescence (XRF) spectrometer (AMPTEK Make, USA) consisting of 0.5 m Silicon Drift Detector (25 mm2, 500 mm Be window), Digital pulse processor and MCA. The Peltier cooled EDXRF spectrometer has been installed. The spectrometer shows FWHM 130 eV at 5.89 keV Mn K X-rays. The data acquisition and analysis software has been loaded on PC/Laptop, which makes it capable for in-vivo field measurements. Geometrical set ups has been designed for use with (i) Mn K x-rays from the 55Fe source and (ii) the K x-rays of various elements, viz., Se, Mo, Zr, Rh, Ag, Sn, and Gd elements excited by the 59.5 keV gamma ray from the 241Am point source (100 mCi) (secondary excitation mode). The geometrical set up has been designed and fabricated using workshop facility available Department of Physics. The spectrometer can be used efficiently in the photon energy range up to 30 keV. The following measurements are being performed/planned using the detector set up: (a) Characterization of the Peltier cooled detector – Measurements of resolution as a function of energy, escape peaks and its theoretical modeling. (b) In-vivo field measurements for articles lying in the Museum are being planned. (c) Angular distribution of the L3 subshell x-ray emission and the scattering cross-section measurements are being planned using this detector and secondary exciter source. Because of the small size, measurements at large angles approaching 180o are possible and the solid angle corrections will be minimized. (b) The procurement of Microfocus XRF spectrometer is under process.

The following are the current investigations taken by the group:

(a) Study of Influence of resonant Raman scattering in the elemental analysis using X-ray emission based techniques. Contribution of near-edge processes (RRS and XAFS) to attenuation of the characteristic X-rays in various elements for the photon energies (Ein) in the region of respective K-shell/Li subshell (i = 1, 2, 3) ionization threshold (BK/BLi). The observed alteration from the theoretical values is attributed to the X-ray Absorption Fine Structure (XAFS) for negative BK/Li - Ein values, and the K-shell/Li subshell resonant Raman scattering (RRS) process for positive BK/Li-Ein values. Systematic of the K-shell/Li

subshell RRS contribution to attenuation of the X-rays are discussed in terms of the respective oscillator density and fraction of electrons available in the K-shell/Li subshell Lorentzian profile of the attenuation element below Ein. Possible matrix effects in the energy dispersive x ray spectrometry due to RRS are also explored. (b) Differential cross sections for Elastic scattering of 59.54-keV γ-rays in elements with 22 ≤ Z ≤ 92 at momentum transfer 0.4 ≤ x ≤ 4.7 Å−1 . The measured differential scattering cross sections are compared with those based on the form-factor (FF)

20

formalism and state-of-the-art S-matrix calculations to differentiate between their relative efficacies and to check angular-dependence of the anomalous scattering factors (ASF) incorporated as correction to the modified form-factor (MF). (c) Alignment of the L3 subshell (J = 3/2) vacancy states produced following photoionization in the Li (i = 1–3) subshells of 79Au, 83Bi, 90Th, and 92U have been investigated through angular distribution of the subsequently emitted L3 subshell x rays. The measurements were also performed for these elements to investigate the effects of external magnetic field (0.60 T) on the L3 subshell x-ray emission. (d) The EDXRF set up has been used in the following applications (i) Heavy metal uptake studies by biomass of immobilized microorganisms (ii) Heavy metal induced physiological alterations in Salvinia natans (iii) Elemental analysis of ground water from different regions of Punjab state (India) using EDXRF technique and the sources of water contamination - Multielemental analysis of the ground water samples from different locations at the boundary between Hoshiarpur and Nawanshahr districts, and Bathinda district of Punjab state (India) was performed. These regions are known to be contaminated by selenium and uranium, respectively. The water samples were analysed using the Energy-dispersive X-ray fluorescence (EDXRF) technique. The water samples from surroundings of the coal-fired thermal power plant in the city and the industrial waste water draining into Sutlej river were also analyzed to investigate the possible sources of water contamination in Bathinda. Agrochemical processes in the water-logged agricultural areas with calcareous soils and use of phosphate fertilizers are favoured sources deterioration of ground water quality in Bathinda district. (iv) Elemental analysis of some ceria-based synthesized catalyst particles is preformed to know the composition of the mixed oxides of some metals with gold. The possibility of the reversible transition from CeO2 to Ce2O3 makes cerium oxide one of the promising materials. Mixed oxide catalytic particlas were synthesized by the research group of Dept. of applied Chemistry, ISM, Dhanbad. (v) EDXRF set up has been used to study of uptake of selenium in different portions of chick pea plant i.e. seeds leaves stem and roots is performed. The research group at Department of Botany, Panjab University, has undertaken these investigations. The experiment was designed for application as phytoremidation. (vi) Thickness determination of CNT (carbon nanotube) films deposited on Si/Glass substrate using the EDXRF set-up involving Mo anode x-ray tube with suitable absorber to reduce the bremsstrahlung and LEGe detector. (vii) Qualitative and quantitative analysis of Eu3+ and Sm3+ ions doped ZnS nanocrystals synthesized at Nano-material research laboratory, Chitkara University, Punjab for the photo-catalytic degradation of environmental organic pollutants. (viii) The analysis of the targets used for nuclear and material science experiments by the students from IUAC, New Delhi.

X-ray production using Heavy ions :The group has also measured the Li-subshell X-ray production cross-sections for 78Pt, 79Au, 82Pb, 83Bi, 90Th, and 92U elements ionized by (i) 19F ions in the energy range 76 - 114 MeV, and (b) 28Si ions in the energy range 84 - 140 MeV. The measurements have been performed at 15 UD Pelletron accelerator at IUAC, New Delhi. Measured cross sections

21

reproduced by Ionisation cross-sections based on the ECUSAR theory and recently recommended set of the Li subshell fluorescence and Coster-Kronig yields after accounting for the effect of multiple ionisation. We are using the accelerator at National Centre for Compositional Characterization of Materials (CCCM), BARC Hydrabad for trace elements analysis and atomic physics. We have performed the experiment on Aerosole, soil and water samples and analysis is in progress. We have also proposed the experiment there to measure the L-subshell ionization cross -sections. We are planning to do the experiment in Feb-March to measure the cross-sections on La-57, Sm-62, Dy-66 and Yb-70 with O-16 and F-19 beams with energies 0.5-1.5 MeV/amu.

B6. Hyperfine Interaction Studies:

The research group has been engaged in the measurement of Hyperfine Interactions i.e. measurement of nuclear electromagnetic moments of the excited states and electric and magnetic hyperfine fields in the magnetic and non-magnetic systems, using PAC (off-line) and PAD (In Beam) techniques. The present facilities include a PAC set up involving multi-BaF2 Scintillators, a Closed Cycle Helium Refrigerator (10K-300K) and Argon Arc Furnace. In the PAC experiments, the activity of the sample cannot be increased beyond a certain level set by the signal-to-noise requirements, the only way to reduce the data collection time, especially for shorter lived radioactive samples, is to increase the efficiency of the spectrometer. The proposed PAC spectrometer with 6 conical LaBr3 detectors and NIM based data acquisition system will be resulting in 30 coincidence spectra simultaneously, with optimised detector-sample geometries covering about 60% of the 4 solid angle and the system having excellent time resolution to resolve the fast interaction frequencies encountered in many experiments. Solid state physics with radioactive isotopes is a prospering and growing field. The established nuclear techniques based upon hyperfine techniques (like PAC, PAD, NMR, NQR, Mössbauer spectroscopy etc have clearly proven the enormous potential of using radioactive probe atoms to characterize defects and impurities in solids. To exploit radioactive probe atoms even more efficiently, implantation energies up to some MeV would be highly desirable. Numerous radioactive species have been employed in the past to attack problems involved with defects or impurities in metals, semiconductors and superconductors.

B7. Nuclear Physics (Theory) Group:Theoretical nuclear physics group at Chandigarh is involved in studying the nuclear dynamics at low, intermediate and relativistic energies. The research topics undertaken are (a) Cluster radioactivity, (b) Fusion, (c) Multifragmentation (d) Nuclear flow and its disappearances, and (e) Particle production at intermediate energies. At low energy, the concern is on the problems of fusion and fission processes whereas at intermediate energies, the work is on the problems of multifragmentation, collective flow and its disappearance, differential flow, elliptic flow, and their connection with nuclear equation of state, rapidity and stopping of nuclear matter and thermalization reached in a reaction. Efforts will be made to compare our theoretical predictions with experimental data. A dynamical cluster decay model is advanced for the formation and decay of hot and rotating compound nuclear formed in light heavy ion reactions. Calculations are made for

22

various compound systems. Studies are being done to include deformations and orientations degree of freedom to generalize proximity nuclear potential and the Coulomb potential. Possible new reactions for synthesis of new and super-heavy elements are pursued.

During 2008-2012 period, we studied various phenomena at low and intermediate energies. Some of these are fusion using proximity potentials for both symmetry and asymmetric reactions. At intermediate energies the process of multuifragmentaton, collective flow and nuclear stopping were investigated. We also studied the entropy production using SACA and MST models.

Fusion-fission dynamics of low energy heavy-ion reactions:

Knowing that Wong formula is a simplification of the dynamical cluster-decay (DCM) of Gupta et al., we have analyzed the Wong model for angular momentum and barrier modification effects in capture cross-sections σcapture, fusion-evaporation cross-sections σevr known for fusion hindrance phenomenon in coupled-channels calculations at sub-barrier energies, and fusion-fission cross-sections σff using the proximity potential due to Blocki et al. with effects of multipole deformations (β2 -β4) and orientations (both co-planer and non-coplaner) included, and the one derived from Skyrme forces based semi-classical energy density formalism in extended Thomas Fermi (ETF) method. One of the interesting result is that the ℓ-dependence in Wong via ℓ-summation is found enough to explain the σcapture for all the reactions studied, but in the case of σevr, a further modification of barriers is required for below barrier energies, affected in terms of either the barrier ''lowering" or barrier ''narrowing" via the curvature constant or choosing different Skyrme forces. Furthermore, the DCM is shown to contain the "barrier lowering" property as its inbuilt characteristic.

The role of deformations and orientations of nuclei is investigated in detail for the exotic cluster radioactive decay using the preformed cluster model (PCM) of Gupta and Malik. An interesting result of this study is that, except for 14C decays where higher multipole deformations up to β4are found essential, the β2 alone is found good enough to fit all other experimental data on cluster-decay half-lives. More recently, this study is extended to the use of relativistic mean field densities in the double folding procedure for constructing the cluster-daughter potential with M3Y nucleon-nucleon interaction containing exchange effects. Interestingly, the RMF-densities based nuclear potential supports the concept of preformation for both the α- and heavier cluster decays. As a by product of this study, the phenomenological M3Y type of effective interaction is shown to be derivable from the RMF theory itself, whose optical potential is shown to describe the exotic cluster radioactive decay process nicely.

Further studies are on fusion-fission dynamics of the compound nucleus Z=117, the nuclear structure effects in Z=117 nucleus, nuclear sub-structure of cluster effects in 112-

122Ba nuclei using the RMF theory, the problem of establishing the magic shells in superheavy mass region by using the reaction data in DCM, entrance channel effects in some reactions, and nuclear reaction cross-sections of exotic nuclei in the Glauber model for the RMF densities.

23

Some of the recent works are reviewed in the following two Reviews: Lecture Notes in Physics 818, “Clusters in Nuclei”, 1 (2010) 223-264, and International Review of Physics (I.RE.PHY.) 5 (2011) 74-87.

The following innovations and new observations are made:

A complete dynamical theory of heavy ion reactions, based on microscopic Skyrme energy density formalism (SEDF), using the semiclassical extended Thomas Fermi (ETF) method, is developed which includes temperature of the compound system and deformations to all higher multi-pole orders and orientations of both coplanar and non-coplanar nuclei. The model developed help us to calculate the fusion cross-sections, barrier modification effects at sub-barrier energies with in one parameter description, the neck length parameter, with nuclear structure effects included, missing in its simplified version, the Wong model. The new results obtained are given as the following observations:

1. Use of a simplified version of DCM, the Wong formula, in SEDF of semiclassical ETF method.

2. Barrier modification effects assessed by using the ℓ-summed extended Wong model for both the “pocket formula” and Skyrme forces based proximity potential derived from ETF method.

3. The role of deformations and orientations in spontaneous exotic cluster decays using PCM.

4. Role of Skyrme forces in capture reactions, for which the Wong model is most suited.

5. Role of co-planar and non-coplanar degrees of freedom in dominantly quasi-fission, equivalently capture, evaporation residue and fusion-fission reactions.

6. Use of RMF densities in cluster decay studies, including the deformation effects.

(C) Condensed Matter Group

C1. Experimental Condensed Matter

Solid state Physics is one of the thrust areas recognised by UGC under CAS. The experimental activities of this group involve materials which are important from applications point of view as well as those that lead to an understanding of basic properties of matter and materials. On-going work involves identification of materials suitable for opto-electronic devices, fabrication and characterisation of semi-conducting thin films and preparation and characterisation of carbon Nanotubes.

During the last decade, this group has made significant contributions in training graduate and post-graduate students as well as research personnel. They have picked up the latest techniques being used by academics, research organisations and industry. At any given point in time there are about 18 Ph.D. scholars, 3-4 M.Sc. students, 2-3 M. Tech. (Nano-science and nano-technology) students and 2-3 M.Phil. students working in these laboratories.

Carbon nanomaterials such as C60 and carbon nanotubes (CNTs) are deposited as thin films on various substrates, irradiated with swift heavy ions at IUAC, Delhi, and characterized by various means. We have also set up an arc discharge unit which can produce C60 as well as CNTs, and has been used mainly as a training equipment for M. Sc. and M.Tech (NSNT) project students. This apparatus is also a part of regular lab. Course for M. Tech. (NSNT). Magnetic properties of nanoparticles of Ni are being studied in collaboration with materials science group at Central Scientific Instrumentation Organisation, Chandigarh, a CSIR lab.

Ion Beams on Materials

The importance of studying the properties of carbon nanotubes (CNTs) under various extreme conditions is underlined by the fact that numerous usages have been envisaged. Some of these conditions are purported to be created by a passing ion beam through the material. We irradiate films of CNTs with swift heavy ions of widely varying energies to simulate these, and find the surprising result that instead of being damaged at the outset, the CNTs are healed (annealed) to better crystallinity when there is a low dose of incident ions.

The following is the summary of the work done during the recent past:

(a) Optical constants of thermally deposited In50Se50 and Ag10(In50Se50)90 thin films:

Thin films of chemical composition In50Se50 and Ag10(In50 Se50)90 are prepared by thermal evaporation technique. The optical properties of these thin films are determined by a method, based only on the transmission spectra at normal incidence, measured over the 400-1000 nm spectral range. The optical absorption edge is described using the indirect transition model proposed by Tauc and the optical band gap (Eg) is calculated from the

25

absorption coefficient (α) by Tauc’s extrapolation procedure. It is observed that the value of refractive index (n) and α decrease and the value of Eg increases after the incorporation of Ag.

(b) Light, Annealing and Plasma induced changes on the electrical properties of a- GaSe Thin films

Thin films of GaSe have been deposited at room temperature on glass substrate by physical vapor deposition technique. These films are irradiated with light for 6 hrs at room temperature using heat filtered white light by using tungsten lamp (1035 lux), annealed at 523K for 1 hr and irradiated with argon- plasma (p~0.2 mbar, I=20mA) for 1 hr. Dark conductivity measurements were made on as-deposited and irradiated GaSe thin films in the temperature range 100-370 K in order to identify the conduction mechanism and the effect of different treatments on its electrical properties. The obtained results revealed two distinct regions. The mechanisms of such regions were analyzed. At high temperatures dc conductivity (σd) obeys the law: ln σ 1/T, indicating conduction in extended states, and at low temperatures, obeys the law ln σ T-1/4, indicating variable range hopping in localized states near the Fermi level. The density of localized states N(EF) and various other Mott’s parameters like degree of disorder (To), hopping distance (R) and hopping energy (W) near the Fermi level is calculated before and after different treatments using dc conductivity measurements at low temperatures. Steady state photoconductivity measurements were done in the temperature range 303-373 K by using heat filtered white light.

(c) Effect of In concentration on the electrical properties of InSe alloy:

InxSe1-x (x = 0.4, 0.5, 0.6) thin films are deposited at room temperature on glass substrates by thermal evaporation technique. The X-Ray diffraction analysis showed that both the as-deposited films In2Se3 and InSe (x = 0.4 and 0.5) are amorphous in nature while the as-deposited films of In3Se2 are polycrystalline. Scanning electron microscopy (SEM) photographs of these samples have been taken. The dc measurements are made on the InxSe1-x films at all concentrations, in the temperature range 100-400 K. The obtained results revealed three distinct regions. Temperature dependence of conductivity are analyzed by three mechanisms, extended state conductivity, conduction in band tail and conduction in localized sites. It is clear from the results, that at high temperatures conductivity mechanism obeys the law ln σ 1/T and at low temperatures: ln σ T-1/4, indicating variable range hopping energy in the localized states near the Fermi level N (Ef). The incorporation of In atoms in Se matrix leads to an increase in the electrical conductivity and decrease in the thermal activation energy. The change in the above parameters has been discussed in terms of the phase transition which is taking place in InxSe1-x thin films.

26

(d) Effect of Bi Addition on the Physical Parameters of a-GeSe Glassy Alloy:

Physical parameters like mean bond energy (<E>), average heat of atomization and average coordination number (<r>) have been calculated. Cohesive energy (CE) is also calculated by using chemical bond approach (CBA) method and electronegtivity is calculated by using Sanderson principle. The glass transition temperature (Tg) has been calculated and it increases as the Bi concentration increases. The results have been explained on the basis of some structural changes which occur after the addition of Bi into the system.

(e) Effect of proton irradiations on amorphous InSe thin film:

Optical parameters have been studied after proton irradiation (fluence: 1 × 1015 and 1 × 1014 ions/cm2)of a-In50Se50 thin films at room temperature in vacuum (~10−6 Torr) at 3 MeV proton energy from Chandigarh Cyclotron. The beam was focused using a circular collimator so that an area of ~0.75 cm2 on the films received a uniform ion dose. Changes in the optical parameters like refractive index (n), absorption coefficient (α), optical gap (Eg

opt), extinction coefficient (k), real and imaginary dielectric constants (ε1 and ε2) are observed in a-In50Se50 thin films prepared by thermal evaporation technique under vacuum. Transmission measurements have been done before and after proton irradiation. The mechanism of optical absorption follows the rule of indirect allowed transition model proposed by Tauc and the optical band gap (Eg

opt) is calculated by Tauc’s extrapolation. It is found that after the proton irradiation, the refractive index, absorption coefficient and optical gap decreases for the fluence 1 × 1014 ions/cm2

and for higher fluence the value of these parameters increase. These results will be explained on the basis of some structural changes occurring after proton irradiations.

(f) On the calorimetric study of chalcogenide Se85Te15 glass:

The calorimetric parameters of Se85Te15 glass has been investigated using differential scanning calorimetry (DSC) in non-isothermal conditions at different heating rates of 5, 10, 15, and 20 0Cmin-1. Double crystallization behaviour is observed at all heating rates. The glass transition temperature (Tg) is found to increase with increase in heating rate (α). The activation energy for glass transition (Eg) and for the both crystallization phases is determined using different empirical approaches for different heating rates. The kinetic parameters are calculated using methods recently developed for non-isothermal conditions. The calculated value of kinetic exponent n indicates one dimensional growth with surface nucleation for first crystallization peak and two (two- and three-dimensional

27

growth) mechanisms are working simultaneously for second crystallization peak. The average value of crystallization reaction order, n is (1.28±0.03) and (3.4±0.5) for the first and second crystallization stages respectively. The average value of Eg, Ec1 and Ec2 are (67.02±1.5) kcalmol-1, (37.93±2.1) kcalmol-1 and (57.11±7.5) kcalmol-1 respectively. Thermal stability and glass forming tendency have also been studied for different heating rates.

(g) Crystallization study of Sn additive Se-Te chalcogenide alloys:Calorimetric study of Se85–xTe15Snx (x = 0, 2, 4 and 6) glassy alloys have been performed using Differential Scanning Calorimetry (DSC) under non-isothermal conditions at four different heating rates (5, 10, 15 and 20°C/min). The glass transition temperature and peak crystallization temperature are found to increase with increasing heating rate. It is remarkable to note that a second glass transition region is associated with second crystallization peak for Sn additive Se-Te investigated samples. Three approaches have been employed to study the glass transition region. The kinetic analysis for the first crystallization peak has been taken by three different methods. The glass transition activation energy, the activation energy of crystallization and Avrami exponent (n) are found to be composition dependent. The crystallization ability is found to increase with increasing Sn content. From the experimental data, the temperature difference (Tp – Tg) is found to maximum for Se83Te15Sn2 alloy, which indicates that this alloy is thermally more stable in the composition range under investigation.

(h) Glass transition and crystallization study of chalcogenide Se70Te15In15 glassDifferential scanning calorimetry (DSC) data at different heating rates (5, 10, 15 and 20°Cmin–1) of Se70Te15In15 chalcogenide glass is reported and discussed. The crystallization mechanism is explained in terms of recent analyses developed for use under non-isothermal conditions. The value of Avrami exponent (n) indicates that the glassy Se70Te15In15 alloy has three dimensional growths. The average values of the activation energy for glass transition, Eg, and crystallization process, Ec, are (154.16 ± 4.1) kJmol–1 and (98.81 ± 18.1) kJmol–1, respectively. The ease of glass formation has also been studied. The reduced glass transition temperature (Trg), Hruby’ parameter (Kgl) and fragility index (Fi) indicate that the prepared glass is obtained from a strong glass forming liquid.

(i) On the crystallization kinetics of In additive Se-Te chalcogenide glassesThe calorimetric parameters of glassy Se85–xTe15Inx (x = 0, 2, 6 and 10) alloys have been investigated using Differential Scanning Calorimetry (DSC) in non-isothermal conditions at different heating rates of 5, 10, 15 and 20ºC/min. It is observed that in these glasses, the glass transition temperature, the onset crystallization temperature and the peak temperature of crystallization are found to be dependent on the composition and heating rates. The glass transition activation energy and crystallization activation energy have been determined using different empirical approaches. The kinetic analysis of the

28

crystallization peak has been performed using Matusita’s model. The values of Avrami exponent (n) and activation energy of crystallization (Ec) are evaluated. The validity of Matusita’s model is ascertained by comparison with the results obtained by Kissinger model and Augis and Banett method as well as their approximations. The activation energy of crystallization is determined by analyzing the data using the isoconversional methods. The present study shows that the activation energy of crystallization varies with the degree of conversion and hence with temperature. Thermal stability and glass forming tendency have also been studied for different heating rates.

(j) Effect of irradiation on the optical properties of a-GaSe thin films:

The effect of laser irradiation (λ= 532 nm), argon plasma treatment (p~0.2 mbar, I=20mA), effect of proton irradiation (1×1014 ions/cm2) and effect of annealing (T = 523K) have been studied on the optical properties of GaSe semi-conducting material. Thin films of GaSe are deposited by physical vapor deposition technique. Optical measurements have been taken at room temperature and the different parameters like refractive index (n), absorption coefficient (α), optical gap (Eg

opt), extinction coefficient (k), real and imaginary dielectric constants (ε1 and ε2), before and after these treatments have been calculated. The mechanism of optical absorption follows the rule of indirect allowed transition and the optical band gap (Eg

opt) is calculated by Tauc’s extrapolation.

(k) Optical nonlinearity in chalcogenide glasses:

Chalcogenide glasses have large values of non-linearity at 1.55 μm, several orders of magnitude larger than the value for conventional silica glass. Recently, third-order optical nonlinearity of chalcogenide glasses has attracted a considerable attention. According to the semi empirical Miller’s rule, third order optical nonlinear susceptibility (χ (3)) can be enhanced with the increase of the refractive index (n). As metal ions play an important role in augmenting the value of ‘n’, the addition of metal ions may rise the value ‘n’ and is expected to improve the value χ(3) comparing with the host material. Thin films of Ge20Se80 and Ag10Ge0.18Se0.72 have been prepared using thermal evaporation technique. Photo-diffusion of Ag metal has also been done on Ge20Se80 thin films. Refractive index (n) has been measured using the transmission data. Third order optical nonlinear susceptibility (χ(3)) have been calculated using the Miller’s formula for all three samples. It has been observed from the results that the addition of Ag into the Ge20Se80 system enhances the value of ‘n’ and χ(3). Increase in these values is more in case of the photo-diffused film. A careful analysis of these results also suggests that the contribution to polarizability from the lone electron pairs is not predominant factor influencing the non-linear properties of Ag metal alloyed Ge20Se80 glasses. Additional factors such as glass structure or density, the presence of unpaired electrons and the presence of defect states must be taken into account.

(l) Non-Ideal p-n junction Diode of SbxSe1-x (x = 0.4, 0.5, 0.6, 0.7) Thin Films:

We have made diodes consisting of the same alloy i.e. SbxSe1-x (x = 0.4, 0.5, 0.6 and 0.7), but change the concentration of Sb metal from 40% to 70% atomic weight percentage. It is observed from the Hall measurements that the nature of charge carriers have changed from p- to n-type at x = 0.6 for SbxSe1-x. We have measured I-V characteristics of four p-n junction diodes i.e. p-Sb2Se3 / n-Sb3Se2, p-Sb2Se3 / n-Sb7Se3, p-SbSe / n-Sb3Se2 , p-SbSe / n-Sb7Se3. We have calculated the parameters as built -in voltage (Vbi), forward resistance (Rf), ideal factor (n), saturation current (Io), breakdown current (IBd) and breakdown voltage (VBd).

(m) Photodarkening Effect in a-(GaSe)90Ag10 Thin Films: The present paper reports the laser induced changes on the optical properties of a-(GaSe)90Ag10 thin films prepared by thermal evaporation technique. Thin film samples, on glass substrate, were exposed to laser light of wavelength λ = 532 nm for different exposure times, tE (tE = 0 s, 500 s, 1000 s and 3000 s). Optical parameters like absorption coefficient and optical energy gap of as- deposited thin film and their laser induced changes were studied at three different times of exposure. The value of absorption coefficient of these thin film increases on exposing the film to laser irradiation. The optical absorption edge shift to lower photon energy i.e. the photo darkening (PD) effect occurs. The results have been explained on the basis of structural changes that are occurring after the laser irradiation.

C2. Condensed Matter (Theory) Group:

Solid state Physics is one of the thrust areas recognised by UGC under CAS. The computational activities of this group involve carbon nano-materials which form currently important area of research. On-going work involves study of properties of carbon nanotubes and clusters of metals and semiconductors using various techniques. We also study anharmonic properties especially in the context of shock wave propagation in materials.

A large number of Ph.D.s have been granted in these areas and a significant number of M.Sc. (project) and M. Tech. (Nano-science and nano-technology) student are working with this group.

Current ActivitiesThe last decade has seen a huge interest in the properties of matter at nanometer scale. Today it is practically (and arguably) the most active area of research in Physical sciences.

Our work mainly consist of predicting/ confirming the structure, dynamics and thermal properties of various carbon materials and other nanosystems such as metal clusters, BN Nanotubes etc., using potential models. We are also using proprietary software to

30

determine electronic structure of these systems. Beginnings have been made in nanofluidics.

Properties of Clusters – Calculations

We are exploring structure and electronic properties of endohedral fullerenes and carbon nanotubes doped with different metals, transition metal and magnetic atoms and their clusters. Apart from this dilute magnetic semiconductors and oxide semiconductors are also studied for their application as spintronic materials. We use various Packages, all using Density Functional schemes. The systems investigated are gold nanocages, endohedral buckyballs and gold clusters with Si doping. All these systems have projected uses in nano-electronics. Two important results have been obtained so far -- the Au-Si system is shown to have a far greater tendency to form monatomic sheets as compared to pure gold, which may have relevance for nano-electronica; the C60 buckyball ia capable of accommodating a large number of N atoms in single bonded configuration, which may have relevance for energy storage material.

Single atom gold chains, which are actually seen to form under an atomic force microscope, have been investigated by an atom- atom potential method using simple molecular mechanics methods. Calculations not only match experimental findings, but predict a few interesting mechanical properties (plasticity) of such monatomic Au nanowires.Our computational efforts are going to see a thrust in electronic structure calculations. This requires cluster computing for which the system needs to be acquired. We also need to do molecular dynamics simulations for which software has to be obtained. All of these are being planned to be included in regular teaching courses (e.g., 'simulation' course under NSNT, 'programming' course under M.Sc. and special paper on nanomaterials for M.Sc. Physics students).

(D) Molecular Spectroscopy Group:

The Molecular Spectroscopy group is working in the following areas:

(1) Porphyrins, which are biologically important molecule and found in heamoglobin, myoglobin, and cytochromes etc. Chlorophyll and Vitamin B12 are also related compounds. We are studying chemical and photo-induced electron transfer processes in porphyrins and their gas sensing properties with the help of vibrational spectroscopic techniques and density functional theory calculations.

(2) Phthalocyanines: These are organic semi conductors and have many practical applications. We are studying their volatile organic chemical sensing properties by spectroscopic techniques and density functional theory.

Initially, we studied the effect of pyridine on the geometrical structure and vibrations of zinc phthalocyanine in order to understand the possible interactions of organic vapours molecules with the phthalocyanine molecules. We have used density functional theory calculations and infrared absorption spectroscopy for this purpose. X-ray diffraction pattern was also recorded in the absence and presence of pyridine. In the presence of pyridine phase of the crystalline zinc phthalocyanine changes from b to a. Some infrared bands show changes in their positions and/or intensities. These

31

changes have been interpreted on the basis of coordination of the pyridine molecule with the central zinc ion. Coordinated pyridine transfers some of its charge to the p electron system of the phthalocyanine ring through zinc ion. Pyridine molecule also distorts the phthalocyanine molecule by pulling zinc ion out of the phthalocyanine plane. Density functional theory also confirms the ligation of pyridine molecule at the fifth coordination site of the central metal ion. Next, we have studied zinc phthalocyanine thin film and chemical analyte interactions by density functional theory and vibrational techniques. For this purpose, thin films of zinc phthalocyanine were deposited on KBr and glass substrates by the thermal evaporation method and characterized by the x-ray diffraction, optical, infrared and Raman techniques. The observed x-ray diffraction and infrared absorption spectra of as-deposited thin filmssuggested the presence of an a crystalline phase. Infrared and Raman spectra of thin films after exposure to vapours of ammonia and methanol had also been recorded. Shifts in the position of some IR and Raman bands in the spectra of exposed films were observed. Some bands also showed changes in their intensity on exposure. Increased charge on the phthalocyanine ring and out-of-plane distortion of the core due to interaction between zinc phthalocyanine and vapour molecules involving the fifth coordination site of the central metal ion might be responsible for the band shifts. Changes in the intensity of bands wereinterpreted in terms of the lowering of molecular symmetry from D4h to C4v due to doming of the core. Molecular parameters and Mulliken atomic charges of zinc phthalocyanine and its complexes with methanol and ammonia had been calculated from density functional theory. The binding energy of the complexes had also been calculated. Calculated values of the energy for different complexes suggested that axially coordinated vapour molecules formed the most stable complex. Calculated Mulliken atomic charges showed net charge transfer from vapour molecules to the phthalocyanine ring for the most stable complex. We have also studied the effects of chemical vapours on the vibrational spectra of nickel phthalocyanine thin films experimentally and theoretically by density functional theory. Effects of chemical vapours on the Raman and infrared absorption spectra of a crystalline nickel phthalocyanine thin films were reported. Transmission electron micrograph of the thin films suggested presence of nano-sized particles of nickel phthalocyanine in the thin film. Some vibrational bands showed changes in their positions and/or intensities on exposure of thin films with chemical vapours. These changes were interpreted on the basis of interactions of the vapours molecule with the central nickel ion and other peripheral atoms of the phthalocyanine ring. Density functional theory calculations were also carried out to determine the probable geometric structures of the complexes of vapour and phthalocyanine molecules. Calculated geometric structures showed in-plane and out-of-plane distortions in the phthalocyanine molecule. Calculations further suggested charge transfer between vapourand phthalocyanine molecules. In contrast to zinc phthalocyanine, this molecule can form six coordinated species with vapour molecules. We have also studied the sensing mechanism of zinc tetraphenylporphine (ZnTPP) towards the methanol, pyridine, diethylamine, dichloromethane, acetonitrile, bromine

32

and NO2 vapours. We deposited thin films of ZnTPP and recorded the resonance Raman and infrared absorption spectra of thin films before and after exposure with diethyl amine/methanol vapours. Positions of some vibrational bands show detectable change on exposure. Changesin the intensity of some vibrational bands of the thin films have also been observed on exposure. Coordination of vapours molecules at the zinc ion and subsequent charge transfer are responsible for the shift in the vibrational bands. Density functional theory calculations have been carried out to determine the probable geometric structures of the porphyrin-vapour complexes. Calculated geometric structures show in-plane and out-of-plane distortions in the porphyrin macrocycle. Calculations also result in charge transfer between vapour and porphyrin molecules. (3) Laser dyes: We are also interested in some laser dyes of xanthene family and

coumarins. Presently, we are studying the salvation dynamics of these dyes with the help of vibrational spectroscopic techniques and density function theory calculations.

(4) We are also working on the vibrational dynamics of some potential radio protective antioxidant and radical reactions.

(E) Mass Spectrometry and Geochronology Group:

Group Members:The group are carrying out the Rb-Sr Isotopic and Geochronological investigations on the granitic and gneissic rocks of the Himalaya. The granitic and gneissic rocks have preserved in them episodes of magmatic and metamorphic activities which occurred over a great span of time from Precambrian to recent, including Himalayan Orogeny. It is not possible to establish and define precisely most of these events by routine geological methods such as the nature of xenoliths present, field relationship with the country rocks, petrographical similarities, structural trends, grade of metamorphism etc. The Rb-Sr isotopic and geochronological studies provide an invaluable tool to unravel many important events such as the ages of some igneous and metamorphic rocks, petrogenetic history, metamorphism, mineral ages, rate of cooling etc. The Rb-Sr age data could be used for correlation of the rocks under study with their possible equivalents in different parts of the Himalaya and also in the Peninsular India. Highlights / achievements of Research Work done by the group : The group has published a number of Rb-Sr isotopic ages for the Himalaya granites and gneisses which provided a new dimension to the interpretation of geological events and completely changed the old conjectural geological thinking about these rocks. Thus when Jaeger et al, 1971 for the first time reported the age of 517± 100 M.Y. for the Mandi granite, it was taken with criticism as most of the geologists at that time considered it to be of Tertiary age (<65M.Y.). When the same age data was confirmed by scientists working in foreign laboratories, it changed the geological thinking. The work of the group led to the recognition of the following main periods of magmatic activity based on Rb-Sr whole rock isotopic ages of the granites and gneisses:

33

a) Ages around 2000 M.Y. The granitic and gneissic rocks of this age group have been reported from Munsiari, Askot, Tawaghat, Namik, Dhakuri, Joshimath-Guptkashi, Hanuman Chatti, Rihee-Gangi, Bhatwari and Naitwar areas of Kamaun-Garhwal Himalaya; Wangtu, Bandal and Baragaon of Himachal Himalaya and Shasho and Lopara Kashmir Himalaya.

b). Ages around 1500 M.Y.

The granites and gneisses of this age group have been obtained from Mayali, Maithana, Chandrapuri, Chamoli and Amritpur areas of Kumaun Himalaya; Baragaon and Nirath of Himachal Himalaya and Kalaktang of Arunachal Himalaya.

c) Ages around 1200 M.Y. The rocks of the age group of about 1200 M.Y. include Koidal gneiss, Gwaldom granite, Baijnath-Therali gneiss, Ramgarh gneiss and Amritpur grey granite of Kumaun Himalaya and Bandal granite and Chor granitic gneiss of Himachal Himalaya.

c) Ages around 500 M.Y. This is the most widely spread age group. The granites and gneisses of the age group of about 500 M.Y. have been reported from Doda and Kishtwar- Thathari areas of Kashmir Himalaya; Mandi,Karsog, Sarangi- Ranga Thach N.E. of Manikaran, Manali, Koksar, Chhotadara, Jaspa, Dalhousie, Akpa, Rakcham-Chitkul-Sangla, Chor and Khadrala areas of Himachal Himalaya and Ranikhet, Champawat, Dudatoli, Vaikrita group north of Tawaghat and Harsil areas of Kumaun Himalaya.

e) Ages around 350 M.Y.

The granitic and gneissic rocks of this age group have been obtained from Dalhousie area of Himachal Himalaya and Masi, Lansdowne and Almora areas of Kumaun Himalaya.

Presently we are carrying out Rb-Sr Isotopic and Geochronological studies on the biotite and muscovite separated from the granitic and gneissic rocks of the following areas from Himachal Himalaya:

1. Manali, Chhotadara and Jaspa

2. Wangtu and Tapri

3. Rakcham, Karcham and Chitkul

This study will provide the

• Thermal history • Rate of uplift • Other geological aspect of these areas.

We are also carrying out Systematic Rb-Sr isotopic studies on the water samples of hot springs from different areas of Himachal Himalaya and rivers Satluj, Baspa, Beas and their tributories and nullahs. This study will give information about

34

• The source material of the water• Sr isotopic constituents• Mineral explorations• Contribution of Satluj, Baspa and Beas rivers to the oceanic Strontium budget• Explanation to the increasing 87Sr/ 86Sr ratio in ocean water even beyond global values • Information about basement rocks of hot water sources and the presence of

radioactive material.

9. ADDITIONAL FUNDING REQUIREDDuring the last CAS-Advisory committee meeting certain additional funds were recommended for the CAS-Program. However no funds were released since then. In view of the continuing requirements as well as additional requirements that have arisen the following list of funding is placed before the committee for discussion.

Items recommended by the Committee in last Meeting

(present estimates given )

HPCC Facility Rs. 15 Lac

Sputter Unit Rs. 3 Lac

HPGe detector electronics module Rs. 3 Lac

Monochromator Accessories and nano-voltmeter Rs. 6 Lac

High Energy Theory Group

Computer/Laptops

Rs. 3 Lac

Mass spectrometer accessories and maintenance Rs. 6 Lac

Teaching Labs Rs 5 lacs

Travel (International & Domestic travel) Rs 5 lacs.

Extension of Building Rs. 50 Lac

New Requirements

Microniser Machine (XRF) Rs. 5 Lacs

Condensed matter Physics lab (Electric wiring and upgradation of Power supply)

Rs. 6 Lacs

Optical-fibre coupled microscope for existing Raman Spectrograph Rs. 30 lacs

Microfocus XRF laboratory (lab. Renovation and UPS) Rs. 3 Lacs

Contribution towards new building Rs 50 Lacs.

121

Total Rs. 190 lacs

Justification of Building funds:

The roof of the Department has undergone severe wear and tear and needs urgent renovation.The

space requirements have increased greatly because of the expansion of the Department in terms

of number of courses, number of undergraduate and post graduate students and Research students

in various research fields. The University has begun the process of approving plans for the new

construction. However funding needs to be arranged from several sources in view of resource

crunch. Therefore the UGC-CAS may consider making aid for this purpose to act as seed money

for the new building.
