用双折叠模型计算了核核碰撞的相互作用势,其中核子-核子相互作用势采用M3Y-Reid和M3Y-Paris形式,交换部分考虑了有限力程的密度依赖的核子-核子相互作用,程序用于重离子散射光学势实部的计算.回顾了折叠模型的普遍特征和讨论了理论计算过程,对各种类型的核子-核子相互作用下计算的相互作用势进行比较,发现双折叠模型对大部分系统相互作用势的实部取得了满意的结果.因此这个工作为重离子相互作用势的折叠计算提供了很好的方法.

The calculations of nucleus-nucleus potential are carried out in the framework of double folding model with M3Y-Reid and M3Y-Paris effective nucleon-nucleon (NN) interactions. The exchange part of the interaction, which is taken to be of finite range and the density dependence of NN interaction, is accounted for in the folding procedure. The results are used as the real part of the optical potential for heavy ion scattering.Besides, some general aspects of the folding model are reviewed and its theoretical processes are discussed.The calculated potentials with all kinds of NN interactions are compared. It is shown that the real parts of the optical potential for a large number of systems are obtained satisfactorily with our double folding model.Therefore, this work provides a promising way for a systematic and comprehensive double folding calculation of heavy ion interaction potential.
