Abstract

High-spin states were populated in [Formula Presented] using the [Formula Presented] reaction at a beam energy of 72 MeV. Two magnetic dipole bands have been observed, both of which contain weak [Formula Presented] crossover transitions. Lifetimes for the stronger of the two bands were measured via the Doppler shift attenuation method. The configuration assignment for this band has been determined from comparison with tilted axis cranking model calculations to be [Formula Presented] and [Formula Presented] before and after the [Formula Presented] band crossing, respectively. The deduced [Formula Presented] strengths decrease rapidly with increasing spin after the [Formula Presented] alignment, which is a characteristic behavior of a shears band.
