Abstract

Excited states in the N=88 nucleus Tb153 were observed up to spin ∼40 in an experiment utilizing the Gammasphere array. The Tb153 states were populated in a weak α4n evaporation channel of the Cl37 + Sn124 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 Tb153 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.
