Abstract
The spectrum of γ-radiation of the radioactive isotope170Lu was studied by means of two Ge(Li) coaxial semiconductor detectors. Around 150γ-transitions belonging to the decay of170Lu were found and their relative intensities were determined. Using the relative intensities of the conversional electrons from other works the internal conversional coefficients and the multipolarities of γ-ray transitions in the170Yb nucleus were established. Twenty new excited levels of the170Yb nucleus were introduced.
A comparison of the experimental results with the predictions of the superfluid and Davydov models is made. The possible existence of Iπ=O− excited states in the level scheme of170Yb is discussed.
