在量子分子动力学模型中与N，Z有关的宏观势对碎片形成的影响

Abstract

基于ＱｕａｎｔｕｍＭｏｌｅｃｕｌａｒＤｙｎａｍｉｃｓ（ＱＭＤ）模型，在Ｓｋｙｒｍｅ类型势，Ｙｕｋａｗａ和库仑相互作用势外，又考虑了与碎片集团的中子、质子数相关的宏观势，即波滴模型中的对称能再加上壳修正能和对修正能．这样的考虑改善了中能重离子反应中集团形成的合理结构。Based on the QMD model, in addition to the Skyrme-type, Yukawa and Coulomb interactions, a macroscopic potential, which is dependent on the neutron andproton number N,Z of the cluster and consists of the symmetrical energy of liquiddrop model and shell and pairing correction energies, has been taken into account.It improved the reasonable structure of the cluster formation in heavy ion reactionswith intermediate energy.中国科学院理论物理学科特别支持费部分资
