Abstract

Fast-rotating N=151 isotones ²⁴⁵Pu, ²⁴⁷Cm and ²⁴⁹Cf have been studied through inelastic excitation and transfer reactions with radioactive targets. While all have a ground-state band built on a νj_15/2[734]9/2^- Nilsson configuration, new excited bands have also been observed in each isotone. These odd-N excited bands allow a comparison of the alignment behavior for two different configurations, where the νj_15/2 alignment is either blocked or allowed. The effect of higher order deformations is explored through cranking calculations, which help clarify the elusive nature of νj_15/2 alignments.
