摘要
在扩展的同位旋相关的Brueckner Hartree Fock理论框架内 ,研究了三体核力对同位旋非对称核物质中质子与中子的单粒子势及其同位旋依赖性的影响 .
Within the isospin dependent Extended Brueckner-Hartree-Fock framework,the three-body force effects on the single particle potentials of a neutron and a proton in isospin asymmetric nuclear matter and their isospin denpendence have been investigated. It is shown that the contribution of the three-body force is repulsive. At low density, i.e., around and below the empirical saturation density, the effect of the three-body force is rather small, while as increasing density, it becomes more and more pronounced. It is also found that at a given density, the three-body effect increases with isospin asymmetry.
