Description
An analysis is made of the recent β+ decay measurements of Garcia et al., in order to see whether the 1981 37Cl(p,n)37Ar measurements of Rapaport et al. are consistent with them. Garcia 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. These uncertainties leave a range of possible values open which we investigate. We find that the experiments are consistent within 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 this range can be narrowed so that the consistency of the two experiments can be conclusively tested
