Abstract
The decay of on-line mass-separated [Formula Presented] has been studied by [Formula Presented] spectroscopy. A definite odd parity and a probable [Formula Presented] are deduced for the high-spin [Formula Presented]-decaying level. The 1116 keV and 1392 keV levels in the [Formula Presented] daughter nucleus are candidates for the bottom of the [Formula Presented] band. There is no support for a previously reported very-low-lying [Formula Presented] level at 871 keV. A [Formula Presented] band built on the new level at 1639 keV is proposed. The lowest-lying two-quasiparticle levels in [Formula Presented] are calculated in the framework of the quantum Monte Carlo pairing model using deformed shell model states. The lowest configurations are associated with an oblate minimum of the potential energy.
