Abstract

Lifetimes for decays linking near-yrast states in ¹⁰⁷Cd have been measured using the recoil distance method (RDM). The nucleus of interest was populated via the ⁹⁸Mo(¹²C,3n)¹⁰⁷Cd fusion-evaporation reaction at an incident beam energy of 60 MeV. From the measured lifetimes, transition probabilities have been deduced and compared with the theoretical B(E2) values for limiting cases of harmonic vibrational and axially deformed rotational systems. Our initial results suggest a rotor-like behaviour for the structure based on the unnatural-parity, h_11/2 orbital in ¹⁰⁷Cd, providing further evidence for the role of this 'shape-polarizing' orbital in stabilizing the nuclear deformation in the A ∼ 100 transitional region.
