Abstract
The charge-exchange (71)a(He-3,t gamma)Ge-71 reaction was used to stud y the spin-isospin (Gamow Teller: GT) excitations relevant to the axia l-vector charged-weak response for solar neutrinos. High-lying GT stat es in Ge-71 with excitation energies up to one MeV above the neutron t hreshold were found to have finite gamma-decay branches to low-lying s tates. The GT strengths for relevant states and absorption rates of so lar neutrinos through the Ga-71(nu, e)Ge-71 and Ga-71(nu,e gamma)Ge-71 reactions were derived. (C) 1998 Elsevier Science B.V.
