Abstract
The167Lu source was isolated from products of spallation reaction induced by 660 MeV protons on tantalum target. The direct and the prompt coincidence spectra of gamma rays from the167Lu decay have been studied with different Ge(Li) detectors. Half-lives of several excited states in167Yb have been measured using the delayed coincidence technique. The internal conversion spectra were investigated with Si(Li) detector and with permanent magnet spectrograph as well. The energies and intensities of more than 400 gamma-transitions were determined. The multipolarities of 225 gamma-transitions were established. The proposed decay scheme of the167Lu is based on coincidence measurements, the analysis of energy sums and reaction data. The states in167Yb are interpreted in terms of the unified model. The role of the Coriolis coupling is discussed.
