Decay of191Re

Abstract

The level scheme of 191 Os has been studied from β-decay of 191 Re. Gamma-ray singles spectra, γ-γ and β-γ coincidence spectra were obtained by using high resolution detectors. A total of 82 γ-transitions observed were assigned in the level scheme of 191 Os consisting of thirty-six excited states up to 1391.89 keV. The level and γ-ray transition properties are discussed in terms of the Nilsson model combining the information from ( d , p ), ( d , t ) reactions and ( n , γ) spectroscopies.
