Ds. Haslip et al., SYSTEMATIC SURVEY OF DELTA-I=4 BIFURCATION IN A-SIMILAR-TO-150 SUPERDEFORMED NUCLEI, Physical review. C. Nuclear physics, 58(5), 1998, pp. 2649-2653
Results are presented of a systematic survey of Delta I=4 bifurcation
in 19 superdeformed bands in A similar to 150 Eu and Gd nuclei. The ma
jority of bands show no sign of this regular oscillation in energy lev
els. The statistical significance of the few examples that exhibit the
effect is examined. [S0556-2813(98)51011-4].
