Isospin effects of the Skyrme potential and the momentum dependent interaction at intermediate energy heavy ion collisions

We improve the isospin dependent quantum molecular dynamical model by including isospin effects in the Skyrme potential and the momentum dependent interaction to obtain an isospin dependent Skyrme potential and an isospin dependent momentum interaction. We investigate the isospin effects of Skyrme potential and momentum dependent interaction on the isospin fractionation ratio and the dynamical mechanism in intermediate energy heavy ion collisions. It is found that the isospin dependent Skyrme potential and the isospin dependent momentum interaction produce some important isospin effects in the isospin fractionation ratioSupported by National Natural Science Foundation of China (10435080, 10447006, 10575075), CAS Knowledge Innovation Project (KJCX2-SW-N02) and Major State Basic Research Development Program in China (G2000077400), the Scienti c Research Funds for the Doctor,University of Shanghai for Science and Technology. the Science and Technological Fund of Shanghai Municipal Education Commission for Selecting and Cultivating Excellent University Young Teachers
