摘要 基于有限程的Gogny相互作用,系统研究同位旋非对称核物质的状态方程(equation of state,EOS)及其单粒子势和它们的同位旋相关性.通过对比各类模型以及实验值,说明现有的D1,D1S和D1N这3组Gogny参数的不足之处,指出探寻新的Gogny核力参数的必要性. Using the finite-range Gogny interaction,the equation of state(EOS) and the single-particle potential as well as their isospin dependence in isospin asymmetric nuclear matter is studied.By comparison with other models and empirical values,we show the limitation of the Gogny interactions D1,D1S and D1N,and necessity of a new parameterization of Gogny interaction.
