Gamow-Teller strength function in 71Ge via the (p,n) reaction at medium energies
Abstract
The Gamow-Teller strength function in 71Ge has been measured by use of the 71Ga(p,n) reaction at Ep=120 and 200 MeV. While a significant fraction of the total strength is associated with excited states located below particle-emission threshold, the first excited state exhibits little strength. Excited-state contributions to the total solar-neutrino capture rate for a 71Ga detector are about 14 solar neutrino units for the neutrino spectrum of the standard solar model and about 3-4 solar neutrino units for representative nonstandard solar models.
