Abstract
Levels in the neutron-rich, odd-mass nucleus have been reinvestigated with Gammasphere by measuring high-fold, prompt coincidence events following spontaneous fission of The ground state band has been extended up to The structure associated with the excitation has been confirmed and extended to higher spin. The band head has been established to lie at 301.8 keV. These results clear up differences between our earlier work and results from another experiment published recently. A new collective band based on a level has been identified for the first time. Some distinct features of the level scheme are discussed.
