7416-keV2+Level inSi28and an Excited Prolate Rotational Band

$\gamma$-ray coincidence measurements have revealed decay modes of the 7416 $2^{+}$ level in ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ to the $0^{+}$ level at 4975 keV (6.3±2.7)% and to the $2^{+}$ level at 1779 keV (4.4±2.3)%. The existence of an excited prolate rotational band in ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ based on either the 4975- or 6691-keV $0^{+}$ states with the 7416-keV level as the $2^{+}$ member has been ruled out on the basis of lifetime and branching-ratio data.
