Abstract
A comprehensive investigation of the excited states of has been carried out through the -ray spectroscopy study of the radioactive decay of , , , and and in-beam studies using the reaction. We use the level structure we determined, to test the interacting boson model. We show that the interacting boson model calculation can account for the observed levels below 3 MeV provided the underlying shell structure is taken into account. A low energy four quasiparticle band is proposed and its mixing with the octupole band is discussed.
