摘要：

The Brueckner-Hartree-Fock approximation extended to include ground-state correlations is applied to neutron matter. Single-particle properties are calculated including neutron mean field, effective mass and mean free path. The main result is a pronounced enhancement of the effective mass at the Fermi surface whose influence on neutron star properties is discussed. (C) 1998 Elsevier Science B.V.
