The excitation energies and spins of the levels in the yrast superdeformed band of 191Hg have been determined from two single-step γ transitions and the quasicontinuum spectrum connecting the superdeformed and normal-deformed states. The results are compared with those from theoretical mean-field calculations with different interactions. A discussion of pairing in superdeformed states is also included.
