Abstract

The γ-ray spectrum of the decay chain 161Er → 161Ho → 161Dy has been studied with Ge(Li) detectors. Results of γ-ray singles and coincidence experiments are reported and a decay scheme for 161Er → 161Ho is proposed. Asymptotic quantum-number assignments are made for several new energy levels, in 161Ho and the results are compared to predictions of the unified model. No evidence was found for the population of three-quasiparticle states in 161Ho. Deexcitation of the 32{72[523], 2+} γ-vibrational state and Coriolis coupling in the 12+[411] rotational band are discussed.
