The Disintegration ofTi45

Abstract

The positron and photo-electron spectra of 3.05-hr. ${\mathrm{Ti}}^{45}$ have been studied. At least 96 percent of the positron transitions are to the ground state of ${\mathrm{Sc}}^{45}$ with a maximum positron kinetic energy of 1.022±0.01 Mev. Less than four percent of the positron transitions are to an excited level of ${\mathrm{Sc}}^{45}$ at 450 kev. In addition, certain longer-lived activities are found in the chemically separated titanium fraction produced by both deuteron and proton bombardment of scandium oxide. Two of the activities are shown to be ${\mathrm{P}}^{32}$ and ${\mathrm{Sc}}^{46}$ impurities.
