热非对称核物质中单粒子性质的温度和动量依赖性

Temperature and momentum dependence of single-particle properties in hot asymmetric nuclear matter

Ch. C. Moustakidis

摘要:

研究了动量相关相互作用对热非对称核物质单粒子性质的影响。特别地,质子和中子的单粒子势以及对称势已经在一个自洽模型中使用动量相关的有效相互作用进行了研究。此外,还从上述模型导出了有效质量的同位旋劈裂。在每种情况下,温度效应都被包括和分析。在本工作中使用的有效相互作用的具体参数化的作用进行了研究。结果表明,对称势的行为强烈地依赖于能量密度相互作用部分的参数化和调节函数的动量依赖性。参数化对同位旋质量分裂的影响不太明显。

英文摘要:

We have studied the effects of momentum dependent interactions on the single-particle properties of hot asymmetric nuclear matter. In particular, the single-particle potential of protons and neutrons as well as the symmetry potential have been studied within a self-consistent model using a momentum dependent effective interaction. In addition, the isospin splitting of the effective mass has been derived from the above model. In each case temperature effects have been included and analyzed. The role of the specific parametrization of the effective interaction used in the present work has been investigated. It has been concluded that the behavior of the symmetry potential depends strongly on the parametrization of the interaction part of the energy density and the momentum dependence of the regulator function. The effects of the parametrization have been found to be less pronounced on the isospin mass splitting.
