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 (Qt) inferred for these new bands. These Qt values are compared to Qt values obtained for previously identified superdeformed bands in 81–83Sr. The low Qt of 2.7 +0.7−0.6 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.
