摘要：
An improved quantum molecular dynamics model is developed. By using this model, the properties of ground state of nuclei from Li-6 to Pb-208 are described very well with one set of parameters. The fusion reactions for Ca-40+Zr-90, Ca-40+Zr-96, and Ca-48+Zr-90 at energies near the barrier are studied by this model. The experimental data of the fusion cross sections for Ca-40+Zr-90,Zr-96 at energies near the barrier are reproduced remarkably well without introducing any new parameters. The mechanism for the enhancement of the fusion cross sections for neutron-rich nuclear reaction near barrier is analyzed.
