Abstract

The Gamow-Teller strength function in ${}^{71}{Ge}$ has been measured by use of the reaction ${}^{71}{Ga} (p, n)$ at $E_{p} = 120 and 200$ 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 ${}^{71}{Ga}$ 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.
