We consider the spin-isospin response of asymmetric nuclear matter. The associated free and RPA polarization propagators, relative to isospin-flipping operators, are analytically evaluated and the new features with respect to the symmetric matter are pointed out. We suggest the relevance of neutron excess for charge exchange reactions in the region of the quasi-elastic peak.

Abstract
We consider the spin-isospin response of asymmetric nuclear matter. The associated free and RPA polarization propagators, relative to isospin-flipping operators, are analytically evaluated and the new features with respect to the symmetric matter are pointed out. We suggest the relevance of neutron excess for charge exchange reactions in the region of the quasi-elastic peak.File in questo prodotto:
