Abstract
The decay of 163 Yb(T 1 2 = 11.4 min) has been investigated with Ge(Li),Si(Li) and NaI(Tl) detectors, a toroidal β-spectrometer and magnetic β-spectrographs by using isobarically separated samples produced by the YASNAPP facility at Dubna. The singles γ-ray spectrum, the conversion electron spectrum, prompt and delayed γ-γ coincidences and β +- γ coincidences have been measured. In all, 110 new γ-ray transitions have been observed. A decay scheme for 163Yb is proposed involving thirty excited states in 163Tm. The first members of the rotational bands 1 2 +[411], 7 2 +[404], 1 2 −[541], 3 2 +[411] and 7 2 − [523] have been identified. Possibilities of interpretation for the high-lying levels are discussed. The Q-value of 163Yb has been determined to be 3370±100 keV.
