Abstract：
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.
