Structure of highly deformedZr102populated in decay of low- and high-spin isomers ofY102

The decay of low- and high-spin isomers of ${}_{}{}^{102}{}_{}{}^{}\mathrm{Y}$ to levels in highly deformed ${}_{}{}^{102}{}_{}{}^{}\mathrm{Zr}$ was studied from mass-separated activity produced by thermal neutron fission of ${}_{}{}^{235}{}_{}{}^{}\mathrm{U}$. Based on γ singles and coincidence measurements, decay schemes for both isomers are deduced. Of special interest are states observed at 894 and 1211 keV that are postulated to be $0_2^{+}$ and $2_2^{+}$, respectively. Possible interpretations of these newly observed levels in terms of β, γ, or spherical bands are given.
