Abstract:
Based on the analyses of successes and shortcomings of Boltzmanntype models and quantum molecular dynamics for heavy ion collisions, the new progress of twobody correlation transport theory and isospindependent transport models for heavy ion collision are proposed.

Abstract:
It′s more and more difficult to synthesis and study new nuclei along the proton dripline by using online isotope separator because of its low efficiency. A specific method of “pγ” coincidence measurement, using the known lowlying “2+→0+(ground state)” γ transition of the “daughter” nucleus in coincidence with its βdelayed proton, could increase the detection sensitivity ...

Abstract:
Swift heavy ion induced effects in condensed matter, the electronic energy loss effects, which mainly include defect creation and latent track formation, anisotropic deformation, partial annealing of defects created by nuclear collisions and phase transformation (amorphization) as well as tentative mokels:the ion explosion spike model and the thermal spike model, are reviewed.

Abstract:
The evolution of radioactivity and poisonousness of the products after nuclear explosion is very important for safety and environmental protection. The detailed study of the evolution of radioactivity of fission products, biological hazard potential, energy deposition and so on was performed by using the new data base and code. The contributions of the main radioactive nuclei and the evolution of radioisotopes in soil and rock are also discussed.

Abstract:
The present status of the study on the neutron production rate, the neutron energy spectrum and the radiative nuclear production from the target spallation in accelerator driven clean nuclear system is presented. The Monto Carlo simulation and the related physics are also discussed. Their further improvement and the suggestions for the work to be done in China are proposed.

Abstract:
The new neutronrich mercury isotope 209Hg has been identified from the separated mercury products producted in 600 MeV 18O+natPb (thick target) reaction. An online, gasthermochromatographic technique and a special detection method were used. Four γ rays following the 209Hg decay were assigned. The halflife of 209Hg was determined to be 35+9-6 s.
