Abstract
High-spin states of were populated via the reactions at 35 MeV and at 55 MeV. Previously known bands have been extended and one new structure has been identified. The rotational alignment behavior of the bands and band crossing systematics have been analyzed. Experimental ratios for the strongly coupled bands have been extracted and compared with theoretical predictions. New results were also obtained for the isotone . The [411]3/2 and [413]5/2 pseudo-spin partner bands were observed in both nuclei. Experimental ratios have been determined in both and . However, the estimated large strengths can be explained without static octupole deformation. The [411]3/2 bands in and have been found identical up to spin , which might be explained by changes in deformation.
