| Abstract: | Comparative Brueckner and Jastrow studies of the properties of nuclear matter are somewhat hampered by the complexities of realistic nucleon-nucleon potentials. To avoid some of these difficulties we investigate a nuclear matter model called S-wave matter, which consists of nucleons interacting via various of the Aviles S-wave delta function potentials. These potentials all fit the two-body S-wave scattering data for energies up to 500 meV. By using Jastrow methods we find two-body contributions to the ground state energy ranging from 18 to 29 MeV, depending on the particular potential used; the results for a given potential are in good agreement with the Brueckner results of Haftel. In addition, there are significant Jastrow three-body contributions, indicating that the equivalent three-body Brueckner contributions should be evaluated. |
