Response of asymmetric nuclear matter to isospin-flip probes
We investigate the RPA response of asymmetric nuclear matter to external fields which induce charge exchange between nucleons, both at zero and finite temperature. Closed expressions are obtained for the RPA response in each spin channel when the nucleon - nucleon interaction is of the Skyrme type....
