Abstract
We report evidence for an excited rotational band in and its mixing with vibrational states. The mean life of the 937-keV ′ state was measured to be 22.8±1.4 nsec, yielding single-particle units for the 75-keV ′ → transition. From in-beam, -ray spectroscopy following the reaction , a strong -ray cascade was observed from an yrast band of levels , ,... to spin in .
