Gamow-Teller strength in theβ+decay ofCa37

Calculations are presented for the Gamow-Teller strength distribution in the ${\mathrm{\beta }}^{+}$ decay of ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ca}$ and compared to results extracted from recent beta decay data and from (p,n) data on the analog nucleus ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$. The strength distribution is shown to be sensitive to the Hamiltonian, and comparison with experiment indicates a need for further improvement in the 1s0d shell Hamiltonian. It also indicates that the quenching of the Gamow-Teller operator in the upper part of the 1s0d shell is similar to that deduced from previous analyses.
