Abstract:
The studies of high spins states of A ～130 transitional I,Xe,Cs and Ba nuclei are reviewed. The variety of nuclear structure, such as proton neutron alignment competition, shape coexistance, band termination, crossing delay, signature inversion, octupole correlation, etc. observed in these nuclei is closely related to that both the valence proton and neutron of these nuclei are located in the h 11/2 subsell and the nuclei are soft against the γ deformation.

Abstract:
The present situation of studies on exotic nuclei far from the β stable line is simply reviewed and then the relativistic mean field study on these nuclei has been carried out. This includes studies on neutron halos and proton halos in light nuclei, on nuclear shell effects of nuclei far from the stability, and on the properties of superheavy nuclei.

Abstract:
The characteristic of the nuclei far from stability and the mechanism of the reactions induced by these nuclei are reviewed. The disscusion includes the structure beyond the dripline and examples of elastic and inelastic scattering,inverse kinematic and nuclear break up, and of subbarrier fusion using radioactive beams.

Abstract:
It is not considered in the previous theoretical models on the complete fusion reactions, though the statistical fluctuation is very obvious. In the present work in framework of the classical trajetory model the Langevin random force is included in the motion equations. The fusion probabilities for the 100 Mo+ 100 Mo和 86 Kr+ 123 Sb reactions are calculated by Monte Carlo sampling of trajectories. The calculated fusion probabilities are also compared with the...

Abstract:
In this paper, the nuclear collision geometry which was considered carefully in the interaction cross sections, surface effects and nuclear deformations is adopted. The energy loss of leading proton in each collision is considered. The transverse energy distributions in high energy p A collisions are obtained. The calculated results are in agreement with the experiment data of 200 GeV/ c p Al, Cu and U collisions.

Abstract:
The calculation of the parameters of RIB produced by the projectile fragmentation and separated by an achromatic spectrometer is firstly summarized. The calculation method to the RSPC(the RIB spectrometer between CSR main ring and the experimental ring) is then described. The final results of the yield, the energy spread and the transversal emittance of some typical RIB has been obtained.

Abstract:
A new measurement of the muon anomalous magnetic moment (BNL E821) aims to obtain a precision of 0.35 ppm which is 20 times higher than that of CERN measurement. This increase in precision will provied a sensitivity to virtual particles into the TeV mass range and open a substantial window for the discovery of new physics beyond the standard model. Meanwhile the ultahigh precision aimed for in the BNL experiment gives unusual challenges in physics and in technology.

Abstract:
The experiment in which 13 C trioctanoin was used as a labeled substrate to diagnose the disease about fat malabsorption was explained and followed by a research on the diagnosis of the same disease with 13 C substrate. Both of the experiments proved effective, moreover the latter would be better since the stable isotope is harmless.

Abstract:
The performance indicatrix of the full scope simulator for Qinshan 300 MW nuclear power unit is described. Main design characteristics of the simulator, including calculation models for its nuclear island, its computer and real time simulation support software, are introduced. Its performance is proved better than the requirement for use only in training operators and therefore, the fullscope simulator could be used for other studying.
