摘要：

A microscopic calculation of the one-body Green function for a realistic model of nuclear matter, including spin and tensor correlations, is presented. The calculation, based on the theory of orthogonal correlated basis functions, takes into account up to two-particle (hole) one-hole (particle) correlated basis-function states in the particle (hole) spectral function. The zeroth order of the ladder approximation for the density response is analysed in both the low- and high-momentum transfer regions. The single-particle strengths are compared with other theoretical estimates and experimental data from (e,e'p) experiments.
