· Canadian Journal of Physics
The beta- and gamma-ray spectra of Os/sup 191/ and Os/sup 193/ were studied with a magnetic beta-ray spectrometer, scintillation spectrometers, and coincidence circuits. The 14-hour isomer of Os/sup 191/ decays via a 0.0742-Mev (M3) transition. Gamma rays of energy 0.0418 (100%, E3), 0.0809 (1%, M1 + E2), 0.1287 (100%, M1 + E2), and 14.6 plus or minus 0.3 day decay of Os/sup 191/ and an extension of the accepted decay scheme proposed. The following 19 transitions were associated with the 31.5 plus or minus 0.5 hour decay of Os/sup 193/: 0.0730 (14%), 0.1068 ( approximately 1%), 0.1393 (10%), (2.2%). The internal conversion coefficients for all the stronger transitions suggest that they are M1 + E2 in character. The decay energy of Os/sup 193/ is 1.132 plus or minus 0.005 Mev. Fermi analyses and beta-gamma coincidence experiments established excited states of Ir/sup 193/ at 0.073, ground state. Six otherwise unclassified weak gamma rays can be accommodated if levels at 0.247, 0.315, and 0.613 Mev are included in the decay scheme. The activation cross sections of Os/sup 184/ and Os/sup 190/ are (2.2 plus or minus 0.5) x 10/sup 2/ and 5.3 plus or minus 2 barns respectively, relative to Seren's value of 1.6 plus or minus 0.4 barns for Os/sup 192/.
