Abstract
Abstract: The decay properties of 162Yb (19.0 min) were studied with Ge(Li) and Si(Li) spectrometers; γ-γ and e-γ coincidence measurements were performed. In contradiction to earlier results, the 44.7 keV γ-ray is found to be mainly an M1 transition, indicating that its initial and final levels are the 2− and 1− members of a K = 1 ground-state rotational band. Nilsson assignments to all levels involved are discussed. An upper limit of 15 ns determined for the half-life of the 163.46 keV state means that the F-selection rule in its decay does not act strongly.
