چکیده انگلیسی
We study the properties of neutron matter using a microscopic equation of state based on the Brueckner-Hartree-Fock (BHF) scheme. The binding energy per nucleon is calculated for different densities and various nucleon-nucleon NN interactions. The results of several microscopic approaches are compared. The BHF calculation appears to be very close to the solutions of the Bethe-Fadeev equations with the gap choice. For comparison purposes, the same calculations are performed for symmetric nuclear matter. The effects of hole-hole contributions and self-consistent treatment within the framework of the Green function are calculated for symmetric matter. In this study, it is proved that the added term (hole-hole) greatly affects the equation of state for symmetric matter.
