Many-body correlations induced by the nucleon-nucleon(NN)interactions among nucleons play an important role in a nu clear many-body system,which make the system much more complicated and have more plentiful properties than a non-inter acting Fermi system.For example,the effect of correlations may leads to the depletion of the nucleon momentum distribution bel ow the Fermi momentum and the population above the Fermi momentum in nuclear matter[1].
