摘要：

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 Ga-71, In-115 and F-19 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 <(nu)over bar>(e) --> nu(e) conversion), as well as the solar-neutrino capture rates for the Ga-71 and In-115+F-19 detectors. Uncertainties regarding nuclear-structure information involved in these calculations are discussed.
