A comparison is made of the recent β+-decay measurements of García et al. and the 1981 37Cl(p,n)37Ar measurements of Rapaport et al. in order to see whether the experiments are consistent. García et al. were not able to determine the amount of Gamow-Teller strength in the isobaric analog state (IAS) or the Coulomb mixing of Fermi strength to a state near the IAS, and were forced to determine the amount of Gamow-Teller strength in the daughter 1371 keV state by making the branching ratios sum to unity. This approach leaves a range of possible values open for these quantities which we investigate. We find that the experiments could be consistent within a theoretically unlikely part of this range. We also examine the effect of this range of allowed values on solar and supernova neutrino cross sections of 37Cl and find weak dependence on the uncertainties described here. We discuss how the consistency of the two experiments can be tested more conclusively.
