In nuclear medium,nuclear many-body correlations,especially the short-range correlations,may lead to the depletion of the nucleon momentum distribution below the Fermi momentum and the population above the Fermi momentum in nuclear matter[1].The depletion of the Fermi sea is expected to be closely related to the hard core and the tensor component of the nucleon-nucleon(NN)interaction[2].It plays an important role in testing the validity of the physical picture of independent particle motion in the mean field theory or the standard shell model and serves as a measure of the strength of the dynamical NN correla-
