Abstract

The γ radiation from the ß- decay of the high-spin isomer in98Y has been studied at the separator JOSEF. A main goal was to get insight into the spins of levels in98Zr which have been interpreted as members of an intruder band based on the 02+ state at 854 keV. The measured γ-γ angular-correlations lead to the assignment of spins of 4 and 3 ℏ to the 2491 and 1844 keV levels, respectively, and contradict their interpretation as the 6+ and 4+ states of the proposed band. For the 2.0s isomer of98Y, the ß{-}-decay properties suggest I=5 with a major configuration [πg9/2,νs1/2(g27/2)0].
