Abstract

Decay studies of on-line mass-separated low-spin Zr83 and Y83 sources were carried out. γ, x-ray, conversion-electron singles and time-multiscale, and γ-γ-t measurements were used to deduce the Zr83 decay scheme with 18 levels up to 1250 keV. The investigations establish the decay properties of Ym83((3/2)) and do not confirm the previously proposed high-spin Zrm83(T1/2=6 s). The low lying structure of Y83 is compared with published theoretical calculations in terms of collective models.
