Abstract:
Liftimes and g-factors of high-spin states in 154Dy, populated in the 110Pd(48Ca,4n) reaction, have been measured by the recoil-distance and the recoil-distance transient field methods, respectively. The experiments were carried out in coincidence mode using the multidetector arrays ESSA30 and TESSA3. A drastic loss of collectivity along the yrast line is observed, consistent with a change from prolate collective structures at low spin to predominantly oblate particle-aligned structures at high spin. The g-factors confirm the alignment of the s-band and indicate contributions of proton alignment at higher spins.
