Observation ofT=2Level inMg24as a Compound-Nucleus Resonance

Abstract

The lowest $T=2\mathrm{}$ level in the self-conjugate nucleus ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ has been observed as a sharp resonance in the once—$T$-forbidden capture reaction ${}_{}{}^{23}{}_{}{}^{}\mathrm{Na}(p, \gamma ){{}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}_{T=1\mathrm{}}^{}{}_{}{}^{}}^{*}$ and in the twice-$T$-forbidden elastic scattering ${}_{}{}^{23}{}_{}{}^{}\mathrm{Na}(p, p_0){}_{}{}^{23}{}_{}{}^{}\mathrm{Na}$. The assignment of $J=0\mathrm{}$ to this level at $E_x=15.436\mathrm{}\pm 0.005$ is confirmed by $\gamma -\gamma$ correlation measurements.
