Abstract

Lifetimes of low-spin excited states in Pd-112 were measured using the recoil-distance Doppler-shift technique. The nucleus of interest was populated in a (110)pd(O-18, O-16)Pd-112 reaction using the Cologne FN Tandem accelerator. Three lifetimes of ground-state band members and one lifetime of the y band were measured. From these lifetimes reduced transition probabilities were extracted and compared to interacting boson model, gamma-soft calculations, and Davydov calculations. The lifetime of the 2(gamma)(+) gives some insights on the nuclear shape and structure of the gamma band. The deduced transition rates show an indicator for a rigid triaxial nucleus as well as more indicators for a gamma-soft nucleus.
