Abstract: (Elsevier)

We report variational calculations of ν 8 models of nuclear matter which contain central, spin, isospin, tensor and spin-orbit potentials. These semi-realistic models can explain the nucleon-nucleon scattering in 1 S 0 , 3 S 1 − 3 D 1 , 1 P 1 and 3 P 2 − 3 F 2 states up to ∼ 300 MeV. The variational wave function has two-body central, spin, isospin, tensor and spin-orbit correlations. The terms in the cluster expansion of the energy expectation value, that do not contain the spin-orbit correlations are summed by chain summation techniques developed for the ν 6 models. Of the terms containing spin-orbit correlations, the two-body and three-body-separable ones are calculated, and the magnitude of the rest is estimated. Results for three phase-equivalent ν 8 models, which differ significantly in the strength of tensor and spin-orbit potentials, are reported. They suggest that simple ν 8 models may not be able to simultaneously explain the binding energy and density of nuclear matter.
