Both experiment and theory yield the result that the ground band of 80Zr is superdeformed with an axis ratio of approximately 3 2. In this work excited bands are considered with Skyrme Hartree-Fock approach. Using the Skyrme 3 interaction an excited spherical state is calculated at an excitation energy of 8.6 MeV and an excited superdeformed band with an axis ratio of about 2 1 is obtained with a band-head energy of 8.5 MeV. Relative to the (excited) spherical state, the ground state band consists of a 12-particle-12-hole state and the excited deformed band consists of a 16-particle-16-hole excitation. Other topics such as the kinetic energy anomaly, the monopole shrinkage, and the Bertsch formula for deformation are discussed.
