• Essential in the modern world– Fission power plants– Medical applications– Analytical techniques– Future energy production – Fusion

• To apply these safely and efficiently need to have accurate and well tested values for many physical quantities

Nuclear Data• Nuclear Data is a separate field of study from

Nuclear Physics• Not research• Aim is produce complete, accurate, tested and

reliable databases suitable for a range of applications

• Thus Nuclear Data forms the basis for many other studies

Perceptions• Most ‘non-Nuclear Data specialists’ assume that

the data exists and are adequate in the same way as a telephone directory exists

• Data are ‘free’• Available for all applications particularly ‘new’

ones• If data exist for fission studies then they should

also be available for fusion!

Reality• Data are not ‘free’• Require extension and improvement as new

applications arise• Since measurement usually made relative to a

standard, as these improve then original data need to be recalculated

• Rather few experts – International collaboration essential

• Core role for a body such as IAEA

Role•Provision of atomic and nuclear data services to scientists worldwide (data libraries, bibliographies, documents) through the internet, CD and other media•Coordination of three international atomic and nuclear data networks •Production of new databases throughCoordinated Research Projects (CRPs) and Data Development projects•Assist developing countries through technology transfer activities

The development and maintenance of nuclear technologies rely on the availability of atomic, molecular and nuclear data

Essential data include:•Energy-dependent reaction probabilities (cross sections)•Energy and angular distributions of reaction products•Atomic and nuclear properties of excited states•Nuclear Structure-Radioactive decay data

Important nuclear structure informationPn : β-strength above Sn

t1/2(AZ+1): sensitive to low-lying β-strength

Precursor

Motivation:

•Beta-delayed neutrons are important for energy production, astrophysics and nuclear theory

•Most of the data available are from precursors coming from fission fragments

•New experimental facilities are available which will be able to produce new precursors in the neutron-rich region

•Last evaluation with theoretical comparisons is from 2002

•There is no database that compiles all relevant data

• A related CM was held at IAEA Vienna, 10-12 October, 2011 , the consultants pointed out the need of a CRP on the topic

• An accurate knowledge of the distribution of the β-decay probability over the daughter-nucleus levels provides information for the understanding of the structure of nuclei • In itself the knowledge of these data is of importance for applications, notably in the fields of nuclear technology and astrophysics

• β-decay is a “simple” process which is very sensitive to the nuclear wave function
