RADIOACTIVE DECAY OF Os$sup 191$ AND Os$sup 191$m
Beta and gamma spectra of Os/sup 191/ were studied using a magnetic double-focusing beta spectrometer and a scintillation spectrometer. The isomeric state Os/sup 191m/ decays through the 74.4 450 deg C in a 0.1 kev (E3/M4 = 50) transition with a half-life T/sub 1/2/ = 13.0 450 deg C in a 0.5 hours. A continuous beta spectrum with E/sub max/ = 147 450 deg C in a 3 kev and the gamma transitions 41.83 450 deg C in a 0.05 kev (E3), 82.5 450 deg C in a 0.3 kev, and 129.4 450 deg C in a 0.1 kev (70% M1 + 30% E2) were observed in the decay of the ground state of Os/sup 191/. The conversion coefficient of the last transition was determined as 1.94 450 deg C in a 0.10. Gamma transitions with energies of 47 kev and 185.8 kev were not observed. (auth)
