Abstract

Four superdeformed bands are reported in ⁸⁰Sr, extending known superdeformation in the ₃₈Sr series down to N = 42. The characteristics of these bands are discussed. Residual Doppler shifts were measured and average transition quadrupole moments (Q_t) inferred for these new bands. These Q_t values are compared to Q_t values obtained for previously identified superdeformed bands in ^81-83Sr. The low Q_t of 2.7_-0.6+0.7 eb obtained for the yrast band in ⁸⁰Sr indicates a reduction in the deformation of yrast superdeformed bands in the series ^80-83Sr with decreasing N, and possibly the onset of triaxiality in superdeformed shapes.
