摘要
In-medium nucleon-nucleon(NN)cross sections at various densities and isospin asymmetries are investigated systematically in the framework of the Brueckner-Hartree-Fock approach.The calculations are based on the exact treatment of the center-of-mass momentum instead of the total momentum approximation employed in previous works^([1]).
