Multiple Superdeformed Bands In Sr, Y, And Zr Nuclei

摘要

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