Description

The β-decay of 37Ca has been studied. The half-life was remeasured with improved precision to be 181(1) ms, and β-delayed γ-rays were observed for the first time. The surprisingly high Γγ/Γp values for proton-unbound states in 37K drastically reduce former discrepancies between the Gamow-Teller strength values B(GT) measured in the 37Ga β-decay and those deduced from the 37Cl(p, n)37Ar mirror reaction.
