Abstract
We show that the superdeformed nuclear states can be described in the framework of the interacting boson model (IBM) with the g-bosons being taken into account in this paper. The Delta I = 4 bifurcation in supe rdeformed rotational bands can be reproduced in the SU(5) limit of the sdg IBM. The perturbation causing the Delta I = 4 bifurcation to emer ge in the Delta I = 2 superdeformed rotational band may possess the SU (5) symmetry.
