Abstract

162 MeV 40Ca ions have been used to Coulomb excite the ground-state band of 159Tb up to spin 252. Lifetimes for levels up to spin 252 have been determined with DSA and recoil distance methods. Multipole mixing ratios for several cascade transitions were extracted from an analysis of γ-ray angular correlation data. Reduced transition probabilities thus deduced in a model-independent way were found to be in agreement with the rotational model with Q0 = 7.41 ± 0.06 e · b and gKgR = 1.377 ± 0.010.
