Lifetimes for decays linking near-yrast states in {sup 107}Cd have been measured using the recoil distance method (RDM). The nucleus of interest was populated via the {sup 98}Mo({sup 12}C,3n){sup 107}Cd 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 behavior for the structure based on the unnatural-parity, h{sub 11/2} orbital in {sup 107}Cd, providing further evidence for the role of this 'shape-polarizing' orbital in stabilizing the nuclear deformation in the A {approx} 100 transitional region.
