Beta decay ofAl24

The ${\beta }^{+}$ decay of ${}_{}{}^{24}{}_{}{}^{}\mathrm{Al}$ has been studied with a Ge(Li)-NaI(Tl) escape-suppression spectrometer. The number of ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ $\gamma$ transitions observed following ${}_{}{}^{24}{}_{}{}^{}\mathrm{Al}$ decay has been increased from 19 to 44. Definite new ${\beta }^{+}$ branches were observed to ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ levels at 105 76, 108 21, and 113 14 keV. An enhanced $E2\mathrm{}$ transition from the $4^{+}$ 9301-keV level to the $2^{+}$ 7349-keV level was sought for and found. A probable 8439→7349 $4^{+}$→$2^{+}$ transition was also observed. The contribution of these new experimental results to an elucidation of the band structure of ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ is discussed.
