We compare the Gamow-Teller strength distributions for the [ital A]=37 system as measured by the [sup 37]Ca [beta][sup +] decay experiment with [sup 37]Cl ([ital p],[ital n]) experiments, considering the effect of suppression of [beta]-delayed protons from the 3.239-MeV state in [sup 37]K. We determine a range of values for the suppression of proton emission from this state for which the two measurements of strength are consistent. Recent studies of this state support this suppression and the amount of suppression is within our allowed range. Using the experimentally determined value for the suppression we are able to determine neutrino cross sections on [sup 37]Cl from [sup 8]B solar neutrinos, supernova neutrinos, and [mu][sup +] decay neutrinos. Our cross section for [mu][sup +] decay neutrinos is found to be 20% larger than the estimates of Bahcall, because of high-lying strength only recently confirmed by the [sup 37]Ca [beta][sup +] decay experiment.
