Abstract
The decay of 193Os has been studied using Ge(Li) detectors and a 50 cmπ√2 spectrometer. Multipolarities and E2/M1 mixing ratios have been determined for 23 transitions. Half-life measurements applying the delayed coincidence technique have given the following mean lives: τ(138.97 keV level) = 108 ± 15 ps and τ(180.17 keV level) = 80 +11 −21 ps. The M1 and E2 transition probabilities obtained are discussed in terms of the core excitation model and the Nilsson model.
