Decay of Ca50

The decay of ${\mathrm{Ca}}^{50}$ has been reinvestigated. The serious discrepancy between various theoretical calculations of ${\mathrm{Sc}}^{50}$ and earlier experimental results has been resolved by the observation of an allowed ${\mathrm{Ca}}^{50}$ $\ensuremath{\beta}$ decay to the 1848-keV level in ${\mathrm{Sc}}^{50}$. The ${J}^{\ensuremath{\pi}}={1}^{+}$ assignment for this state and its $\ensuremath{\gamma}$-ray branching ratio are in good agreement with the recent theoretical treatment of ${\mathrm{Sc}}^{50}$ by Hughes and Soga.
