Four new superdeformed bands have been found in the nucleus 86Zr. The good agreement between experiment and configuration-dependent shell correction calculations suggests that three of the bands have triaxial superdeformed shapes. Such unique features in mass A∼80 superdeformed bands have been predicted, but not observed experimentally until now. A fourth band in 86Zr is interesting due to a fairly constant and unusually high dynamic moment of inertia. Possible interpretations of this structure are discussed.
