Abstract

High-spin states in the cross-conjugate pairs of nuclei [Formula Presented] and [Formula Presented] have been investigated using the reaction [Formula Presented] at a laboratory energy of 125 MeV. Coincidence spectra, in some cases gated by charged particle detection, allow the yrast level schemes of all four nuclei to be extended, up to the [Formula Presented]-shell band termination at [Formula Presented] and [Formula Presented] in [Formula Presented] and [Formula Presented] and beyond to [Formula Presented] and [Formula Presented] in [Formula Presented] and [Formula Presented] Opposite-parity bands in [Formula Presented] and [Formula Presented] were observed up to [Formula Presented] and [Formula Presented] respectively. Lifetimes derived from DSAM measurements provide [Formula Presented] and [Formula Presented] values for transitions among the higher levels of each of the nuclei. These are compared with earlier measurements and with [Formula Presented]- and [Formula Presented]-shell model calculations. No model calculations have been published for the opposite-parity bands, but their level spacing and reduced transition rates support a spectator nature of the [Formula Presented] hole.
