Abstract
The positive-parity band of has been extended up to and the lifetimes of the high spin levels of this band have been measured. The deduced transition rates decrease with increasing spin until . Beyond this spin, the observed transition rates are substantially small and remain nearly constant. This is a novel observation for a shears band. The observed features have been described within the framework of the shears mechanism with a principle axis cranking calculation.
