Abstract

The reaction Ga71(p,n)Ge71 has been studied at Ep=35 MeV with a high-resolution time-of-flight system. Individual cross sections to the states at 0.0, 0.175, and 0.500 MeV, which are directly related to solar-neutrino absorption in a proposed Ga71 detector, have been determined. The cross sections for the 0.0- and 0.175-MeV states are nearly equal, contrary to systematics in this mass region. As a result the absorption of solar neutrinos is estimated to be 40% greater than previously calculated.
