Description
The charge-exchange excitations of superfluid odd-A nuclei are studied within the framework of the self-consistent finite Fermi-system theory. The pairing blocking effect due to the odd quasiparticle, the effective NN-interactions both in the particle-hole (ph) and particle-particle (pp) channel, and also the ph-continuum are taken into account. Gamow-Teller strength functions of 71Ga, 115In and 19F nuclei are calculated and compared with those extracted from experimental spectra of (p,n) reactions. The total capture cross sections of the reactor electron antineutrinos are calculated (assuming complete anti νe →νe conversion), as well as the solar-neutrino capture rates for the 71Ga and 115In+19F detectors. Uncertainties regarding nuclear-structure information involved in these calculations are discussed. ((orig.))
