Abstract: The nucleonnucleon cross sections in symmetric nuclear matter were investigated in the framework of the extended Brueckner-Hartree-Fock(BHF) approach with Argonne V14 two body interaction. The influences of the ground state correlation and the rearrangement contribution of the threebody force (TBF) on the cross section have been obtained and discussed separately for identical and nonidentical nucleon collisions. It is shown that the magnitudes of the cross section are increased by the effects of the ground state correlation in low momentum transfers,and are suppressed in medium with increasing density when the rearrangement contribution of the TBF force is considered.
