Proposed Solar-Neutrino Experiment UsingGa71

A solar-neutrino experiment that uses ${}_{}{}^{71}{}_{}{}^{}\mathrm{Ga}$ as a detector can distinguish between broad classes of explanations for the discrepancy between prediction and observation in the ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$ experiment. A radiochemical experiment with the required amount of ${}_{}{}^{71}{}_{}{}^{}\mathrm{Ga}$ is feasible.
