Abstract
The lifetimes of excited states in the yrast band in up to have been measured to high precision by means of the Gammasphere spectrometer using the coincidence recoil distance technique. The reaction at a beam energy of 185 MeV was used. The data were analyzed using the differential decay-curve method and transition quadrupole moments were extracted. The quadrupole moment was found to gradually increase by 15% of its value before the first alignment, after which it drops to a constant level 90% of the value. Detailed comparisons are made with previous measurements and Ultimate Cranker calculations.
