Abstract:
The importance of synthesis of new nuclei far from stability is concisely recounted. The prograsses on synthesis of the new nuclides and the main methods used for producing new nuclei far from stability in the intermediate and heavy mass region is summarized. The half lives of some new nuclides synthesized in china are compared with those calculated based on the gross theory and the microscopic theory. Some examples for transport and chemical separation of the nuclear reaction products...

Abstract:
The present status of experimental studies of the total reaction cross sections of exotic nuclei are reviewed. A detector system used for measuring the total reaction cross section of radioactive ions is described. The energy calibration of detectors, particle identification and possible experimental results are discussed.

Abstract:
The Yrast band energy spectra of even even nuclei 120～130 Xe and 124～130 Ba are calculated by using the O (6) limit of IBM1 containing three body potential. It shows that the backbending characteristics in the Yrast bands can be described fairly by O (6)+ V 3 .

Abstract:
Deuterion deuterion tight bound states model about the mechanism of so called “nuclear cold fusion” is proposed. To solve the stationary Schrodinger equation with combination potential which contains Coulomb barrier and square well potential from nuclear force for the system containing two deuterions, the wave functions, the energy eigenvalues of the probable tight bound states and the existence condition of the tight bound states are obtained. In the case of ground...

Abstract:
Based on revised BBK theory, triple differential cross sections (TDCS) have been calculated for ionization of Li + (ls) by electron impact. A coplaner, equal energy, fixed re1ative angle kinematics are chosen and the particular case where the scattered and ionized electrons emerge perpendicular to each other is emphasized. The incoming electron state is considered by a Coulomb wave from the long range...

Abstract:
The U-Pu cycle in accelerator driven subcritical reactor is studied by means of new data library and code. The satisfactory neutronics results are obtained by calculating the reactor power, critical value, gamma and neutron flux and evolution of fissioning nuclear density. The detailed analysis is also presented.

Abstract:
The Hg products produced in the bombardment of natural lead targets by 18 O beam of 8.4 MeV/u were separated by means of an off line gas thermochromategraphic device. The coincident gamma spectra and time successive single γ ray spectra were measured. Except the already known γ rays, nine new γ rays assigned to the transitions between the known levels of 208 Tl were observed.
