摘要With the supersymmetry scheme including many-body interactions, a parametrization of the excitation energy of superdeformed (SD) states is proposed. The identical SD bands with DeltaI = 4 bifurcation, Gd-149(1) -Gd-148(6) - Eu-148(1), are investigated. Quantitatively good results are obtained. The result shows that the parametrization can describe the identical SD bands and the DeltaI = 4 bifurcation simultaneously. It suggests that the DeltaI = 4 bifurcation in the SD bands may have a bearing on a perturbation exhibiting the SO(5) [or SU(5)] symmetry in the mean field and the identical bands may be interrelated with the supersymmetry.
