Abstract

The properties of neutron matter are investigated in the framework of the extended Brueckner–Hartree–Fock approximation at zero temperature. Self-consistent calculations using different realistic interactions are reported for pure neutron matter. In this contribution, all the self-energies are calculated self-consistently. Using the self-energy, k-mass is evaluated using realistic NN interactions. Furthermore, the effect of hole–hole contributions is examined. We found that the hole–hole ladder brought about a non-negligible contribution.
