核子相对论微观光学势、薛定谔等效势和平均自由程对核密度及温度的依赖关系

DEPENDENCE OF THE NUCLEON RELATIVISTIC MICROSCOPIC OPTICAL POTENTIAL,THE SCHRO ¨DIGER EQUIVALENT POTENTIAL AND THE MEAN FREE PATH ON TEMPERATURE AND DENSITY IN THE RELATIVISTIC MODEL

在Ｗａｌｅｃｋａ模型的基础上，应用热动力学理论和ＤｉｒａｃＢｒｕｃｋｎｅｒＨａｒｔｒｅｅＦｏｃｋ方法，研究了有限温度不同密度下核子相对论微观光学势及其相应的薛定谔等效势和平均自由程计算结果表明，核子薛定谔等效势和平均自由程对核密度的依赖相当敏感。

The nucleon relativistic microscopic optical potential,the Schro ¨dinger equivalent potential and the mean free path at finite temperature in nuclear matter with different nuclear density are studied on the basis of Walecka′s model,the thermo dynamics and the relativistic Dirac Brueckner Hartree Fock approach.The calculated results show that the dependence of the nucleon Schro ¨dinger equivalent potential and the mean free path on nuclear density are fairly sensitive and the dependence on nuclear temperature become more sensitive when nuclear density is larger.
