摘要：

The rotational band in I-121 that initiates on the pi-h11/2[550]1/2- orbital was observed to terminate via coincidence gamma-ray studies following the Cd-114(B-11, 4n) reaction. The band termination occurred at I-pi = 39-/2. Total-Routhian surface calculations reveal an yrast noncollective oblate state (gamma = +60-degrees) at h-omega = 0.36 MeV which consists of an aligned pi-h11/2(pi-g7/2)2(nu-h11/2)2 configuration with I-pi = 39/2-; this shape change from collective prolate to noncollective oblate provides an explanation for the observed band termination.
