One-boson exchange potential and nuclear matter properties

Abstract

The binding energy and saturation density of nuclear matter have been calculated for our momentum dependent OBEP by the reference spectrum method of Bethe et al. The binding energy is calculated to first order in the Brueckner-Goldstone reaction matrix using self-consistent hole state energies in the effective mass approximation and zero intermediate-state potential energies. The second (Pauli term) and higher-order correction terms of the reference spectrum method have been included; the latter in the geometric series approximation of Dahll et al. The potential energy contribution from first, second and third order are roughly in the ratio 80 : 20 : 2. A binding energy of −11.2 MeV per particle was found at a density corresponding to the Fermi momentum k F = 1.55 fm −1.
