Abstract

Measurements of the total thick-target yields of γ rays deexciting the first 2+ excited states of Os192,190,188,186,184 following Coulomb excitation by helium, oxygen, and sulfur ions have been made. These measurements were compared with theoretically calculated yields in order to extract linear combinations of the static electric quadrupole moments of the 2+ states. The results were compared with the measurements of Pryor and Saladin of the absolute moments of Os192,190,188 in order to obtain the best combined values for these three isotopes, as well as absolute values for Os186,184. These values are -0.50 ± 0.20, -0.95 ± 0.19, -1.32 ± 0.43, -1.47 ± 0.54, and -2.4 ± 1.1, respectively. For the isotopes Os192,190,188,186 the B(E2,0+2+) values determined in the experiment agree with published values to within 10%. The B(E2,0+2+) value of Os184 was previously unknown and was determined to be 3.20 ± 0.62 e2b2. The results are also compared with the model calculations of Kumar and Baranger and found to be in good agreement.
