ΔI=4 bifurcation in a superdeformed band: Evidence for a C4 symmetry

Abstract

The moment of inertia of the yrast superdeformed band in Gd149 exhibits an unexpected bifurcation at high rotational frequency. States differing by four units of angular momentum show an energy shift of about 60 eV. This indicates the remnant of a new quantum number associated with the fourfold rotational symmetry.
