Some properties of superdeformed nuclei

Nuclear superdeformation is studied theoretically using both simple models and more realistic numerical calculations. From the simple models general rules are formulated about the shell structure of the nucleus at large deformation, its affinity for reflection asymmetric or necked-in distortions and its response to rotation. The numerical calculations are based on realistic single-particle schemes and indicate that important trends in superdeformed nuclei may be understood from the simpler considerations. Particular attention is focussed on the 2:1 prolate configuration. (Auth.)
