Abstract

$Δ I = 4$ bifurcation has been observed in two superdeformed bands, the newly discovered yrast superdeformed band of $^{148} Eu$ , and a previously known excited band in $^{148} Gd$ . Both of these bands have moments of inertia that are identical to the yrast band of $^{149} Gd$ , the first superdeformed band in which this bifurcation was observed. This first observation of $Δ I = 4$ bifurcation in identical superdeformed bands provides a crucial test of recent models.
