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