    "abstract": "The history and importance of superdeformation in nuclei is briefly\ndiscussed. A simple two-level model is then employed to obtain an elegant\nexpression for the branching ratio for the decay via the E1 process in the\nnormal-deformed band of superdeformed nuclei. From this expression, the\nspreading width Gamma^downarrow for superdeformed decay is found to be\ndetermined completely by experimentally known quantities. The accuracy of the\ntwo-level approximation is verified by considering the effects of other\nnormal-deformed states. Furthermore, by using a statistical model of the energy\nlevels in the normal-deformed well, we can obtain a probabilistic expression\nfor the tunneling matrix element V.",
