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 the Microball 4π detector arrays. For 15 bands in these nuclei, average transition quadrupole moments have been measured with high accuracy, using the Doppler-shift attenuation method. Among these are the newly observed superdeformed bands in 83,84Y, which are “isospectral” with the bands in 82,83 Sr. These “isospectral” bands have nearly identical transition quadrupole moments. Two of the bands in 81Sr interact and cross transitions between them are observed. The present measurements place stringent conditions on configuration assignments for the bands obtained from two types of mean-field calculations, leading to a consistent understanding of the mass ∼80 superdeformed bands. The assignments for different bands arise from one or more nucleons occupying the N0=5h11/2 intruder orbital.
