Proposed theoretical collaboration

China Side

• Common interests among theoretical groups

• Possible collaboration between theory and experiment

Common interests among theoretical physicists

• Structure and reaction of dripline nuclei (extreme isospin)

• Superheavy nuclei ( heaviest)• High-spin state (extreme spin)• Electron (lightest) scattering on unstable nuclei

• Hadron Physics • High-energy nucleus-nucleus collision

1. Nuclear structure and reaction of dripline nuclei

• Exotic light nuclei (halo, skin, shell, deformation)• Shanghai group, Lanzhou group, CIAE…• Beijing group, Nanjing group, SJTU, …• RIKEN, RCNP, Tokyo group, Kyoto group…

• We had good collaboration on structure of halo and skin nuclei...

• We can promote further visits for physicists and students.

Theoretical side:good collaboration

• Many Chinese physicists worked in • RIKEN, RCNP, JAEA, Tokyo, Kyoto…

• Example (theory) : Profs. Z. Y. Ma, • Zhongzhou REN, J. Meng, Y. M. Zhao, S. G.

Zhou, J. D. Bao, F. S. Zhang,….• collaborated with Japanese physicists : • Profs. Toki, Otsuka, Sakurai, …

2. superheavy nuclei

• Experiment: RIKEN, JAEA(JAERI), Lanzhou

• Theory: a lot of nuclear physicists are working on superheavy nuclei in China

• China side: Lanzhou group (IMP), Nanjing group (NJU), CIAE, Beijing group(PKU, BNU…),Shanghai.

• In China we often have the conferences of superheavy nuclei.

• We can promote further collaboration between theory and experiment

3. high spin states

• There is good collaboration between Lanzhou group and JAEA group (JAERI group).

• There are persons in CIAE and Beijing group who are also working on high-spin states.

• More collaboration is also possible.

4. Electron scattering on unstable nuclei

• Electron-RI scattering experiments will be available in RIKEN.

• This will bring new opportunity on structure of unstable nuclei (halo, skin, shell,…)

• Some theoretical researches are useful for future experiments.

• Electron-RI scattering experiments: accurate for charge distributions (i.e. proton-halo…)

Suggestions for electron-RI scattering

• In order to prepare the electron-RI scattering experiments in RIKEN, more theoretical researches on electron-RI scattering are needed.

• Collaboration between theory and experiment is also useful.

5. Hadron physics

• China side: IHEP, Lanzhou group, Beijing group, Nanjing group…

• My colleagues in China are interested in experiments at Spring-8: pentaquark...

• They hope that there is collaboration • between China side and Japan side.

6. High-energy nucleus-nucleus collision

• China side: Shanghai group, Beijing group • Wuhan group, Hefei group, CIAE…

• Physicists in China are interested in • collaboration with Japanese colleagues.• They will talk about it in free speech of this

section.

Summary (1)

• China side: we had good collaboration.• Possible work for future collaboration:• Visits among physicists with common interests• Participations of related conferences in Japan• Theoretical work for experiments in Japan

• Support each other on researches (Referee…)• I, as a referee of international journal,

suggested the citation of Japanese’s article.

Summary (2)

• China side: we have the fund to invite Japanese colleagues to visit China for a short period

(weeks)• China side: we can support Japanese colleagues

to participate the conferences in China

• For long-period visits (months), we can apply for collaborating researches.

Thanks

• Some Theoretical physicists will

talk about their special suggestions

for future collaboration.
