摘要
通过引进基态关联和同位旋自由度的区分 ,推广了Brueckner Hartree Fock理论方法 ,并应用于同位旋非对称核物质 ,系统地研究了在整个同位旋自由度范围内核物质的状态方程和单粒子特性及其同位旋效应 .还研究了微观三体核力对同位旋非对称核物质性质及其同位旋效应的影响 ,定量讨论了三体力效应与相对论性平均场理论及Dirac Brueckner方法的联系 .主要给出了同位旋相关的Brueckner Hartree
In this serial work, the Brueckner-Hatree-Fock approach has been extended by intro- ducing isospin degree of freedom and by including ground-state correlations in neutron and proton mass operators. The obtained isospin dependent extended Brueckner-Hatree-Fock approach has been applied to investigate the single-particle properties and their isospin depndence of isospin-asymmetric nuclear matter. The effect of a microscopic three-body force on the properties of asymmetric nuclear matter and its connection to the relativistic corrections from relativistic mean field theory as well Dirac Brueckner-Hartree-Fock approach have also been studied. In this paper, the isospin dependent extended Brueckner-Hartree-Fock approcach has been derived explicitly.
