Microscopic calculations of charge-exchange nuclear modes

Microscopic calculations of nuclear states excited by means of charge-exchange reactions and involving spin and isospin degrees of freedom, in particular, of the Gamow-Teller and the spin-dipole resonances, are discussed. The framework is a fully self-consistent nonrelativistic spherical quasiparticle random-phase approximation constructed on top of the Hartree-Fock-Bardeen-Cooper-Schrieffer approach. Our results are compared with available experimental data, and a critical discussion is attempted
