Abstract
A new superdeformed rotational band has been observed in Er-154 using the E uroball Ge detector array. The new band and the one previously observed can be understood as based on coexisting superdeformed structures at prolate a nd triaxial shapes, respectively. The observation resolves long-standing di fficulties in the theoretical interpretation of superdeformed states in Er- 154.
