摘要Based on the Improved Quantum Molecular Dynamics Model the fusion reactions of Ca-40,Ca-48+ Zr-90,Zr-96 are studied by making a more rigorous treatment of the initial condition. The study shows that: (1) the calculated fusion cross sections for all four reactions of Ca-40,Ca-48+ Zr-90,Zr-96 are in good agreement with experiment data; (2) the sub-barrier fusion for the neutron-rich reaction Ca-40+Zr-96 is substantially enhanced as compared with the other three reactions. In order to understand the reason why the sub-barrier fusion of the neutron-rich reaction Ca-40+ Zr-96 is enhanced as compared with the non-neutron-rich reaction Ca-40+ Zr-96 and that of the neutron-rich reaction Ca-48+ Zr-96 is not enhanced, the further investigations are carried out, those are: the dynamic fusion barriers for four reactions, the relation between dynamic fusion barrier and nucleon transfer and the relation between nucleon transfer and corresponding reaction Q value. It has been found that positive Q value leads to the strong nucleon transfer which reduces the dynamic fusion barrier and enhances the sub-barrier fusion cross section.
