Abstract/Description: Excited states in the N = 88 nucleus 153Tb were observed up to spin ∼40 in an experiment utilizing the Gammasphere array. The 153Tb states were populated in a weak α4n evaporation channel of the 37Cl + 124Sn reaction. Two previously known sequences were extended to higher spins, and a new decoupled structure was identified. The πh11/2 band was observed in the spin region where other N = 88 isotopes exhibit effects of prolate to oblate shape changes leading to band termination along the yrast line, whereas 153Tb displays a persistent collective behavior. However, minor perturbations of the very highest state in both signatures of this h11/2 band are observed, which perhaps signal the start of the transition towards band termination.
