摘　　要：为更好地研究重离子核反应中的团簇效应,利用反对称化分子动力学模型(AMD),分别采用AMD和AMD-FM2种不同版本系统模拟计算了入射能为15 MeV/nucleon的40Ca+12C反应的初级衰变和次级衰变过程,通过比较同一反应的分析过程来对比2种系统版本的差异,经过对比,2种系统对初级衰变和次级衰变的分析过程有明显区别.In order to study better the cluster effect in heavy ion nuclear reaction,the primary decay and secondary decay processes of 40Ca+12C reaction with incident energy of 15 MeV/nucleon were simulated by AMD and AMD-FM systems,using the antisymmetric molecular dynamics(AMD)model.The differences between the two versions of the system were compared by comparing the analysis process for the same reaction.By comparison,the analysis process of the primary decay and the secondary decay of the two systems were significantly different.

关 键 词：AMD 衰变 重离子核反应
