RFA susceptibility of asymmetric nuclear matter at finite temperatures with skyrme interactions

We investigate the thermal RPA response of asymmetric nuclear matter interacting through various Skyrme interactions characterized by the value of the effective nucleon mass. Our study concentrates on the evolution of collective states according to the variations of the transferred momentum, tempera...
