β-delayed γ-ray emission inCa37decay

We detect β-delayed γ rays emitted in ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ca}$ decay and use these results plus our previous work on β-delayed proton yields to calculate B(GT) values for the ${}_{}{}^{37}{}_{}{}^{}\to _{}^{37}{}_{}{}^{}$K transitions. We compare these results to the isospin-analog B(GT) values inferred from a high-resolution ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$(p,n) study. Although the new β decay and (p,n) results remove some of the previously noted discrepancies between B(GT) values measured in ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ca}$ decay and those inferred from ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$(p,n) cross sections, significant discrepancies remain.
