Conversion electrons in the decay of191Os

Internal conversion electrons in the decay of¹⁹¹Os have been measured with a 30 cm double focusing spectrometer. The transition energies of (129.27±0·07) keV, 82.5 keV, (46.90±±0.06) keV and (41.76±0.02) keV are given together with the corresponding internal conversion line intensities. It was found that the mixture of the 129 keV transition was 87% M1+13% E2. The previously proposed decay scheme is supplemented by the 46.90 keV transition.The authors would like to thank to M. Vobecký and A. Matalka for preparing the electrodeposited sources.
