Equation of state for neutron matter Original Research Article

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.
