Abstract

High spin states in [Formula Presented] have been investigated using the [Formula Presented] and [Formula Presented] reactions, respectively. γ rays were detected using the EUROBALL IV [Formula Presented] and EUROGAM II [Formula Presented] arrays. The results have enabled the negative parity yrast band, built on the [Formula Presented] orbital at low spin, and the lowest lying [Formula Presented] bands to be extended to higher spins. The positive parity, [Formula Presented] bands in [Formula Presented] and the positive parity, [Formula Presented] band in [Formula Presented] can be interpreted, with the aid of cranked Nilsson-Strutinsky calculations, as examples of smoothly terminating bands in valence space based on both signatures of the [Formula Presented] configuration, where [Formula Presented] for [Formula Presented] respectively. The favored [Formula Presented] bands of these configurations are predicted to terminate at [Formula Presented] and [Formula Presented] respectively, and experimentally the bands are observed to within two transitions of these terminating states. The data for the positive parity, [Formula Presented] band in [Formula Presented] do not allow any firm conclusions to be made regarding the high spin structure of this band. The positive parity bands in [Formula Presented] have a different structure at high spin compared with the lighter nuclei. In this case the bands may be interpreted in terms of a [Formula Presented] configuration relative to a [Formula Presented] core.
