Abstract

The nucleus [Formula Presented] was studied using the [Formula Presented] reaction at a beam energy of 105 MeV. An extension of the band built on the [Formula Presented] orbital was observed to exhibit a band crossing at a rotational frequency of 0.511 MeV with an associated alignment of [Formula Presented] This alignment is interpreted as being due to a pair of [Formula Presented] neutrons. Total Routhian surface calculations have been carried out which confirm that the shape of this nucleus changes from oblate at low spin to a triaxial prolate shape at intermediate spin.
