We calculate nucleon-nucleon cross sections in the nuclear medium with unequal densities of protons and neutrons. We use the Dirac-Brueckner-Hartree-Fock approach together with realistic nucleon-nucleon potentials. We examine the effect of asymmetry in neutron and proton concentrations and find that it can be significant for scattering of identical nucleons. Numerical results are included for potential applications in transport equations.
