Abstract
High-spin states in were studied using the early implementation phase of the Gammasphere array and the “Microball” charged-particle detector system. A cascade of nine rays with a dynamic moment of inertia which is characteristic of superdeformed rotational bands in the region has been identified and assigned to . The measured transition quadrupole moment of the band corresponds to a prolate quadrupole deformation of and confirms the superdeformed nature of this band. This is the first direct experimental confirmation of the existence of the predicted superdeformed shell gap at particle number.
