Lifetime measurements of strongly deformed rotational bands in Pm133
Abstract
We have measured lifetimes and deduced deformation parameters for rotational bands in Pm133 by the Doppler-shift attenuation method. A strongly coupled band based on the configuration with a hole in the g9/2 orbital has deformation parameter β2=0.40 (5), which is comparable to or larger than typical superdeformed bands in the A∼130 region. We observe this band in Pm133 down to its I=K=9/2 bandhead. Calculations with a configuration-dependent …
