在重离子碰撞过程中， 基于重质量的弹核轰击轻质量靶核有大量中等质量碎片向前发射的逆运动学效应， 利用同位旋相关的量子分子动力学观察和研究了重离子碰撞过程中同位旋效应的灵敏性． 计算结果表明在所选能区， 中等质量碎片的多重性与带电粒子总数之间的关联是提取介质中核子核子碰撞截面的灵敏观测量， 而此时对称势的同位旋效应却不明显．
During heavy ion collisions, the inverse mass kinetic effect of mass-based nuclear bombardment of light mass target nuclei with a large number of medium-mass fragments forwards was observed. The isokinetic-related quantum molecular dynamics was used to observe and study the effects of heavy ion collisions Isotactic sensitivity. The calculated results show that the correlation between the multiplicity of medium-quality fragments and the total number of charged particles in the selected energy region is a sensitive observation of the nucleon-nucleon collision cross section in the extracted medium, but the isospin effect of the symmetrical potential is not obvious at this time.
