Measurements of Gamow-Teller (GT) transition strengths provide information both about the nature of the weak interaction and about the structure of nuclear wave functions. A recent measurement of the {Beta}-delayed proton decay of {sup 37}Ca resulted in a GT strength distribution which disagreed strongly with the results from a forward angle {sup 37}Cl(p,n){sup 37}Ar experiment. Both results should be identical as long as isospin is a good quantum number. The largest disagreements between the two experiments were found at excitation energies below the isobaric analog state at 5.0 MeV. It has been noted that the discrepancies could be removed if the level at 3.24 MeV in {sup 37}K predominantly decays through the {gamma}-channel rather than the proton channel. Therefore, we have measured the corresponding resonance at 1.42 MeV in the reaction {sup 36}Ar(p,{gamma}){sup 37}K. The implications with regard to the GT distribution below the IAS will be discussed.
