ABSTRACT: We study the equation of state (EOS) of symmetric
nuclear and neutron matter within the framework of the Brueckner-Hartree-Fock
(BHF) approach which is extended by including a density-dependent contact
interaction to achieve the empirical saturation property of symmetric nuclear
matter. This method is shown to affect significantly the nuclear matter EOS and
the density dependence of nuclear symmetry energy at high densities above the
normal nuclear matter density, and it is necessary for reproducing the
empirical saturation property of symmetric nuclear matter in a nonrelativistic
microscopic framework. Realistic nucleon-nucleon interactions which reproduce
the nucleon-nucleon phase shifts are used in the present calculations.
