Average Approximation

The second-order perturbation term in nuclear matter is reduced, for the most general nonlocal potential, to a triple quadrature. A kinematic function of three variables which includes all kinematic effects of the Pauli principle is defined and evaluated analytically. An improved angle average approximation for nuclear matter calculations is derived and found to be very accurate for evaluating the Pauli correction in the reference spectrum method.

Second Order Perturbation Theory

The second-order perturbation theory of nuclear matter is extended to the case where the neutron and proton densities are different. The symmetry coefficients given by the force of Tabakin and that of de Tourreil and Sprung are computed in second order.
