Abstract

The nucleus 134Ce has been investigated by means of γ and e spectroscopic methods. Four side bands in addition to the ground band have been identified. Previous g-factor measurements indicate that the 10+ isomer and the band built on it as well as the band causing backbending have a h112 two-neutron configuration. This fact may be interpreted as a shape coexistence in the framework of the triaxial cranked shell model. The 10+ isomer may be an yrast trap of prolate deformation with an asymmetry parameter of γ = −120° (“Lund convention”) whereas the other band probably has an oblate deformation with γ ≈ −60°. A part of the level scheme of 134Ce shows no band structure. These levels may be connected to the intrinsic motion of the nucleus. They can be explained in terms of weak coupling.
