Abstract

The charge-exchange (71)a(He-3,t gamma)Ge-71 reaction was used to study the spin-isospin (Gamow Teller: GT) excitations relevant to the axial-vector charged-weak response for solar neutrinos. High-lying GT states in Ge-71 with excitation energies up to one MeV above the neutron threshold were found to have finite gamma-decay branches to low-lying states. The GT strengths for relevant states and absorption rates of solar neutrinos through the Ga-71(nu, e)Ge-71 and Ga-71(nu,e gamma)Ge-71 reactions were derived
