Abstract
The cross section σ(Eν) for solar-neutrino capture by the 76Ge nucleus is calculated. The effect of Gamow-Teller resonances on the rate of neutrino capture in the reaction 76Ge (ν, e−)76 As is studied. It is shown that the contribution of high-lying Gamow-Teller resonances to the charge-exchange strength function increases the rate of solar-neutrino capture by 25% to 50%, depending on the normalization method and on the inclusion of the quenching effect.
