摘要：

The momentum distribution and the quasi-hole strength in symmetric nuclear matter have been calculated for two densities in the framework of the Brueckner-Bethe-Goldstone theory. A separable version of the Argonne v14 has been used as realistic NN interaction in the self-consistent procedure to determine the g-matrix and the corresponding mean field. The results for quasi-hole strength have been compared with other calculations and also with the hole-state spectroscopic factor extracted from recent (e, e'p) knock-out reactions on Zr-90 and Pb-208. On the basis of the hole-line expansion higher-order contributions to the momentum distribution have been included in the calculations resulting in a better fulfillment of the Migdal-Luttinger theorem.
