Abstract

A decoupled rotational band with an average dynamical moment of inertia [Formula Presented] [Formula Presented]/MeV has been observed to high spin in [Formula Presented] [Formula Presented]. The measured quadrupole moment of [Formula Presented] eb is as large as that of the superdeformed band in [Formula Presented]. The large deformation and decoupled character of the band suggests that the odd neutron occupies either the [Formula Presented] orbital or the [Formula Presented] intruder orbital. This is the first example of a superdeformed band extending to high spin below [Formula Presented], a neutron number that has long been considered as the boundary for superdeformation in the [Formula Presented] mass region.
