Abstract

The nuclei [Formula Presented] and [Formula Presented] have been studied at very high spins via the [Formula Presented] reaction. Several new rotational bands were observed, four in [Formula Presented] and two in [Formula Presented] The [Formula Presented] moments of inertia calculated from the observed [Formula Presented]-ray energies are very small and almost constant, indicating that these bands are triaxial. Cranked Nilsson-Strutinsky calculations reproduce the general behavior of the bands, supporting this interpretation and suggesting an approximately constant [Formula Presented] value of [Formula Presented] over a large spin range up to the highest observed spins. These bands and a few similar bands in other nuclei of the [Formula Presented] region are a unique example of almost undisturbed triaxial bands.
