Abstract
The energy level scheme for the low-lying collective levels of are reasonably described by an asymmetric rotor with and . To further investigate possible triaxial structures in , we have measured elastic and inelastic scattering angular distributions for excitation of the lowest three excited states in at an bombarding energy of 67 MeV in the angular range . The measured cross sections have been analyzed using coupled channels calculations assuming that behaves as (1) a symmetric rotor and (2) a triaxial rotor. Because of the fact that the and states in are unresolved, difficulty occurs in distinguishing between the two models. Considering to be a triaxial rotor, however, does yield a simple description of the bound states and scattering to the low-lying collective levels.
