Abstract
Excited states in , populated in spontaneous fission of , were studied by use of the eurogam2 multidetector array. Spins and parities of the ground state and the 66.0-, 152.1-, and 458.5-keV excited levels, reported previously, were changed based on conversion-coefficient and angular-correlation measurements. Octupole deformation reported previously in is dismissed, and we explain the near-yrast structure of in terms of rotational bands built on the [413], [411], and [523] orbitals.
