Abstract
The moment of inertia of the yrast superdeformed band in 149Gd exhibit s an unexpected bifurcation at high rotational frequency. States diffe ring by four units of angular momentum show an energy shift of about 6 0 eV. This indicates the remnant of a new quantum number associated wi th the fourfold rotational symmetry.
