Decay ofSc48

Abstract

A previously unreported gamma ray of approximately 175 keV and 7% abundance was found in the decay of ${\mathrm{Sc}}^{48}$. This necessitates a revision of the decay scheme to include a second beta group with an end-point energy of approximately 475 keV. The presence of the new gamma and second beta group was confirmed by means of gamma-gamma and beta-gamma coincidence counting techniques.
