Abstract:
The production, and process of separation and identification of new neutronrich nuclei with mass number A>170 were analyzed. The advantages of producing new isotopes in this mass region by lighter heavy particles on heavy targets were summarized. It is put forward an improvement method that a laser ion source and multilayer target combining with gas jet transport method can be used on online isotope separator.

Abstract:
A corrrelated threebody continuum wavefunction proposed by Brauner et al has been recently modified further to allow for threebody effects by introducing Somerfeld parameters (Berakdar and Briggs). The triple differential cross sections for electron impact ionization of He+ in coplanar equalenergy sharing and fixedrelative angle geometry are calculated. The initial channel wavefunction involves a Coulomb wavefunction due to the long range Coulomb attraction between the incident...

Abstract:
The stability of the main parameters at HIRFL accelerator complex, which is important to get high extraction efficiency of the beams from cyclotrons has been studied. The RF amplitude stability and the stability of main magnetic field are the key parameters. The reasonable requirements for the parameters at HIRFL and the measures to reach them are proposed.

Abstract:
Since 1995, the sputter ion source has been tested on the 2 MV tandem accelerator in the Institute of Modern Physics. During the experiment some important improvememts on the source were performed. The running procedure has been progressively perfect. With this vaurce, the stable Li, C,O ion beams can be delivered by the accelerator for long period.

Abstract:
Based on the tightbinding molecular dynamics, the structural, thermodynamical and collision properties are systematically studied for Nan. Present claculations are successful in reproducing some of the experimental data and in agreement very well with some other ab initio calculations. We also investigate the transition from solidlike phase to liquidlike phase with increasing temperature for this finite system and the stability of dimer (Nan)2 formed in cluster collisions.

Abstract:
Mechanisms affecting multicomponent material sputtering are complex. Isotope sputtering is the simplest in the multicomponent materials sputtering. Although only mass effect plays a dominant role in the isotope sputtering, there is still an isotope puzzle in suputtering by ion bombardment. The major arguments are as follows:(1) At the zero fluence, is the isotope enrichment ejectionangleindependent or ejectionangledependent? (2)Is the isotope angular effect the primary or the ...

Abstract:
A CT technique applied to ICF experiments has been studied and it has been used to analize the measured Xray in laserplasma experiments at “XingguangⅡ” device. The threedimensional distribution of the Xrays in targets is reconstructed and useful results are obtained. This shows that the CT technique can be applied to ICF experiments.
