  • Correlated basis function perturbation theory and the formalism of cluster expansions have been recently employed to obtain an effective interaction from a state-of-the-art nucleon nucleon potential model. The approach based on the effective interaction allows for a consistent description of the nuclear matter ground state and nucleon-nucleon scattering in the nuclear medium. This paper reports the the results of numerical calculations of different properties of nuclear and neutron matter, including the equation of state and the shear viscosity and thermal conductivity transport coefficients, carried out using the effective interaction.
  • The problem of pairing in semi-infinite nuclear matter is considered in the Brueckner approach. Equations for effective pairing interaction in semi-infinite matter are derived for the case of the separable representation of realistic NN interaction. The propagator of two noninteracting particles in a semi-infinite potential well is calculated numerically. The equation for effective interaction is solved for a model 8-shaped NN interaction, which correctly reproduces NN scattering in the low-energy limit. 15 refs., 10 figs.

  • We study the effect of the momentum dependence on the thermal properties of excited dilute nuclear matter in the Boltzmann approximation. The optical potential, mean field, [ital k] mass, pressure, and incompressibility are calculated. We improve on an earlier approximate treatment and find, in most cases, relatively small quantitative differences in the behavior of the calculated observables. An exception is the [ital k] mass, which acquires a temperature dependence in the improved approximation. Phase diagrams for nuclear matter are presented and the transition of hadronic matter to quark-gluon plasma is studied.
