TRIAXIAL BANDS IN CE-133

An experiment performed on the early implementation of the GAMMASPHERE array to populate the high-spin states in Ce-133 has revealed the pre sence of several rotational structures with energy spacings of Delta E (gamma)similar to 100 keV. Some of these bands exhibit a backbend at ( h) over bar omega similar to 0.6 MeV and are observed to high rotation al frequencies-(h) over bar omega similar to 0.85 MeV. These character istics are very different from those observed for any other rotational bands in this mass region. The properties of these new structures wil l be discussed within the framework of cranked Strutinsky-Woods-Saxon calculations. Currently, these bands are thought to be based on triaxi al nuclear shapes.
