Abstract：
The momentum- and density-dependent coupling constants for scalar and vector fields are proposed.The saturation properties of the nuclear matter,the experimantal data of the energy-dependent optical potential and the mean free path in nuclei can be reproduced simultaneously.The in-medium n-n elastic cross section has been calculated for different densities and energies.The results show that it is important to take the density dependence of the n-n cross section into account.
