Abstract：
The isospin dependent quantum molecular dynamics model has been further developed by considering shell effect and the fusion mechanism near Coulomb barrier is studied by using the improved model. For light reaction system, the fusion excitation function can be described very well by using the improved model, which is consistent with the experimental data. At the same time, the experimental capture cross section for heavy reaction system can be reproduced basically.Especially for the region near or below barrier, it can also be described reasonably by using the improved model. As a further test for the model,the nucleus-nucleus interaction potential is also calculated, and compared with the proximity potential as well.
