Density and temperature dependence of nucleon-nucleon elastic cross section

Qingfeng Li, Zhuxia Li, Enguang Zhao

The in-medium neutron-proton, proton-proton (neutron-neutron) elastic scattering cross sections (${\sigma }_{np}^{\ast }$, ${\sigma }_{pp(nn)}^{\ast }$) are studied based on the effective Lagrangian of de…
