Multiple Superdeformed Bands In Sr, Y, And Zr Nuclei

Multiple superdeformed bands in the nuclei 80–83Sr, 82–84Y, and 83,84Zr have been studied in a backed‐target experiment using the Gammasphere and Microball detector arrays. For 15 bands in these nuclei, average transition quadrupole moments (Qt) have been measured accurately. Among those are two pairs of “isospectral” bands and the Qt values obtained in each case are nearly identical. The measured Qt values and dynamical moments of inertia place stringent conditions on configuration assignments for the bands obtained from mean field calculations.
