Popis: Mean lifetimes have been measured for states up to Ipi =18+ in the yrast band of 132Ce using the recoil distance method. In the vicinity of the first backbend, caused by the alignment of a pair of h11/2 protons, a pronounced drop in the collectivity is observed. This contrasts with the anomalously high B(E2) values measured in 130Ce. The results are compared with the theoretical predictions of the MONSTER code.
