Description
An improved Quantum Molecular Dynamics (QMD) model is proposed and the fusion reactions 40,48Ca + 90,96Zr are studied by using this model. With our improved QMD model, the ground state properties and their time evolution of nuclei from 6Li to 208Pb can be reproduced reasonably well and the excitation functions of fusion cross section for reactions 40Ca + 90Zr and 40Ca + 96Zr at near barrier can be reproduced remarkably well with the same set of parameters. Authors found that the N/Z value in neck region is clearly large at the early stage of neck formation in neutron-rich nuclei reactions, which cause the lowering of dynamical Coulomb barrier and thus enhance the fusion cross section
