Abstract
The spectrum of neutrinos produced by the beta decay of in the sun is computed including forbidden corrections to the weak interactions. The total cross section for absorption by of neutrinos is (1.06±0.1)× . The uncertainty is determined by calculating the cross section using different measured spectra for the alpha particles that result from the decay of to and by varying the transition matrix elements consistent with the branching ratios measured using delayed protons emitted in the beta decay of .
