Energy Levels of Ti48 from the Decay of Sc48 and V48

Abstract

The gamma rays following the decay of ${\mathrm{Sc}}^{48}$ and ${\mathrm{V}}^{48}$ have been investigated by means of threefold coincidence techniques. In the case of ${\mathrm{Sc}}^{48}$, it was found that within the limits of experimental error all of the decays occur via a three-gamma cascade. In ${\mathrm{V}}^{48}$, although the decay occurs primarily via a two-gamma process, a small three gamma contribution was detected. By twofold coincidence measurements, the 2.2-Mev gamma ray of ${\mathrm{V}}^{48}$ decay was found to be in cascade with the 0.99-Mev gamma ray. Level schemes are proposed for both decays.
