The self-energy of nucleons in asymmetric nuclear matter is evaluated employing different realistic models for the nucleon-nucleon interaction. Starting from the Brueckner-Hartree-Fock approximation without the usual angle average in the two-nucleon propagator the effects of the hole-hole contributions are investigated within the self-consistent Green’s function approach. Special attention is paid to the isospin dependence of correlations, which can be deduced ... إقراء المزيد

In the present paper we studied the EOS in the framework of the BHF approach following Ref. 32, starting from the symmetric nuclear matter and the pure neutron matter, using the two-body forces and the inclusion of the suggested TBF. We illustrate the correction for the two-body forces, which fit in perfect way the TBF results of Ref. 32. In ... إقراء المزيد
