Superdeformed Bands in 80Sr and the Evolution of Deformation in Sr Isotopes

Devlin, M.; LaFosse, D. R.; Lerma, F.; Sarantites, D. G.; Baktash, C.; Birriel, I.; Jin, H. Q.; Lee, I. Y.; Macchiavelli, A. O. and Rudolph, Dirk LU , et al. (1997) In Physics Letters. Section B: Nuclear, Elementary Particle and High-Energy Physics 415(4). p.328-334
Abstract
Four superdeformed bands are reported in Sr-80, extending known superdeformation in the Sr-38 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 Sr81-83. The low Q(t) of 2.7(-0.6)(+0.7) eb obtained for the yrast band in Sr-80 indicates a reduction in the deformation of yrast superdeformed bands in the series Sr80-83 with decreasing N, and possibly the onset of triaxiality in superdeformed shapes.
