Abstract
The available data on levels in have been reevaluated and interpreted using recently published information on band structure in this region. A calculation in the interacting boson model framework suggests that the isomer is a spherical state with the configuration. This assignment implies that the bandhead at is a state, with the highly probable configuration. The level structure of is well reproduced by coupling the levels of its both spherical and deformed odd- neighbors and the origin of the isomeric states is understood.
