  This work presents an approach to nuclear spin-isospin response, which is
capable of describing the overall strength distribution up to high excitation
energies, including the fine structure of the low-lying strength, and resolving
the long-standing quenching problem. The model is a covariant realization of
the nuclear field theory and based on the self-consistent extensions of the
covariant energy density functional (CEDF) theory. Results of the recent
calculations for spin-isospin response of ordinary and exotic medium-mass
nuclei are presented and discussed.
