Beta decay ofSc51to states inTi51

${}_{}{}^{51}{}_{}{}^{}\mathrm{Sc}$ was produced with the ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}(\alpha ,p){}_{}{}^{51}{}_{}{}^{}\mathrm{Sc}$ reaction at $E_{\alpha }=18\mathrm{}$ MeV and pneumatically transferred to a shielded counting area. The $\beta$ decay scheme of ${}_{}{}^{51}{}_{}{}^{}\mathrm{Sc}$ was determined from measurements of the $\gamma$ singles and $\gamma -\gamma$ coincidence spectra using ${50-\mathrm{c}\mathrm{m}}^3$ Ge(Li) detectors. This investigation yielded a more accurate determination of the ${}_{}{}^{51}{}_{}{}^{}\mathrm{Sc}$ half-life (12.4 ± 0.1 s), the observation of previously unknown $\beta$ branches to ${}_{}{}^{51}{}_{}{}^{}\mathrm{Ti}$ levels at 2691, 2731, 2919, 3062, 3237, 3619, 4095, 4186, and 4881 keV, and the assignment of new levels in ${}_{}{}^{51}{}_{}{}^{}\mathrm{Ti}$ at 3062, 4095, and 4186 keV. In addition, the decay scheme provides parity assignments and spin restrictions for a number of states in ${}_{}{}^{51}{}_{}{}^{}\mathrm{Ti}$.
