Abstract：
Within the supersymmetry scheme including many body interactions and a perturbation possessing the SO (5) (or SU(5))symmetry on the rotational symmetry, the superdeformed (SD) bands of the odd A nuclei in A≈190 mass region are investigated systematically. Quantitatively good results of the γ-ray energy spectra and the dynamical moments of inertia are obtained. It shows that the supersymmetry approach is powerful in describing not only the generic rotational property, but also the ΔI=4 bifurcation and the identical bands in SD states simultaneously.
