利用同位旋相关的量子分子动力学模型,对中能重离子反应产物中的同位素分布进行了研究,重点分析了平均场中的动量相关作用和两体碰撞的同位旋相关性对于产物中同位素标度现象的影响．结果表明:这两个因素均明显减小了同位素标度参量α的值,从而减弱了同位旋标度参量α对两个反应系统同位旋差的依赖性．
Isotope-related quantum molecular dynamics model was used to study the distribution of isotopes in heavy ion reaction products. The correlation of momentum in the mean field and the isospin correlation of two-body collision were mainly analyzed. The impact of the degree phenomenon. The results show that both of these two factors significantly reduce the value of the isotope scaling parameter α, which reduces the dependence of the isospin parameter α on the isospin of the two reaction systems.
