Abstract

We study the properties of symmetric nuclear matter and pure neutron matter at zero temperature within the framework of the Brueckner theory using tabulated values of effective masses and depth of the single-particle energies. These tabulated values are chosen according to the work of Hassaneen et al, 2011. The Brueckner–Hartree–Fock approximation plus a density-dependent contact term as a three-body force are used to achieve the empirical saturation property of symmetric nuclear matter. The three-body force provides a strong enhancement of pressure and incompressibility in good agreement with relativistic approaches. Realistic nucleon-nucleon interactions which reproduce the nucleon-nucleon phase shifts are used in the present calculations. Good agreement is obtained in comparison with the experimental data.
