| 摘 要： | 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,当核密度增大时对核密度的依赖变得更为敏感.

| Abstract: | The nucleon relativistic microscopic optical potential,the Schrödinger 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 Schrödinger 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. |
