英文摘要	We show in this paper that the superdeformed nuclear states can be described with a four parameter formula in the spirit of the perturbated SU(3) limit of the sdg IBM. The E2 transition gamma-ray energies, the dynamical moments of inertia of the lowest superdeformed (SD) bands in even-even Hg, Pb, Gd, and Dy isotopes, and the energy differences Delta E-gamma-Delta E-gamma(ref) of the SD band 1 of Hg-194 are calculated. The calculated results agree with experimental data well. This indicates that the SD states are governed by a rotational interaction plus a perturbation with SOsdg(5) symmetry. The perturbation causing the Delta I=4 bifurcation to emerge in the Delta I=2 superdeformed rotational band may then possess SOsdg(5) symmetry.
