基于重质量弹核（放射性核或稳定核）打轻质量靶核的逆运动学效应，即 反应产物主要集中在小角度的优点，利用同位旋相关的量子分子动力学模型，探 寻了对于中能重离子碰撞过程中同位旋效应灵敏的物理观测量．计算表明，在 入射能量约大于８０ＭｅＶ／ｕ能区，中等质量碎片多重性随发射带电粒子总数之间 的演化是提取介质中同位旋相关的核子－核子碰撞截面的灵敏物理量．
The inverse kinematics effect of light mass target nuclei based on heavy mass bombs (radionuclides or stable nuclei), ie, the advantages of the reaction products being mainly concentrated at small angles, utilize the isospin-related quantum molecular dynamics model to explore the kinetic energy- Isotactic sensitive physical observations during heavy ion collisions. Calculations show that the evolution of the multiplicity of medium-quality fragments with the total number of charged particles at an incident energy of more than about 80 MeV / u is the sensitive physical quantity of the isospin-related nucleon-nuclear collision cross section in the extraction medium.
