Lifetimes of 8+, 10+ and 12+ states in fourteen rotational and quasi-rotational doubly even nuclei have been measured with a Doppler broadened lineshape technique. In addition, the lifetime of the 14+ state in 164Dy has been determined. The B(E2) values have been extracted and compared with rotational model predictions. All the 8+ → 6+ and 10+ → 8+ transitions and most of the 12+ → 10+ transitions are well described by the model. However, the 12+ → 10+ transitions in 162Dy, 164Er and 170Yb are found to be retarded significantly. It is Suggested that the hindrances may be related to the known backbending properties of two of these nuclei.
