Calculations are presented for the Gamow-Teller strength distribution in the {beta}{sup +} decay of {sup 37}Ca and compared to results extracted from recent beta decay data and from ({ital p},{ital n}) data on the analog nucleus {sup 37}Cl. The strength distribution is shown to be sensitive to the Hamiltonian, and comparison with experiment indicates a need for further improvement in the 1{ital s}0{ital d} shell Hamiltonian. It also indicates that the quenching of the Gamow-Teller operator in the upper part of the 1{ital s}0{ital d} shell is similar to that deduced from previous analyses.
