Properties of the superdeformed bands of odd-odd nuclei in A~ 130 mass region are investigated systematically within the supersymmetry scheme including many-body interactions and a perturbation possessing the SO(5) (or SU(5)) symmetry on the rotational symmetry. The obtained ?-ray energies, the dynamical moments of inertia, and energy differences agree with experimental data. It shows that this approach is quite powerful in describing odd-odd nuclei in 130 mass region.

With the supersymmetry scheme including many-body interactions and a perturbation possessing the SO(5) (or SU(5)) symmetry on the rotational symmetry, the superdeformed bands and ?I=4 bifurcation of odd-odd nuclei in A~ 190 mass region are investigated systematically. Good results for the ?-ray energies, the dynamical moments of inertia, and energy differences are obtained. It shows that this approach is quite powerful in describing odd-odd nuclei in the region.

With the supersymmetry scheme including many-body interactions, the global property and the ?I = 4 bifurcation in the superdeformed (SD) bands of odd-odd nuclei in A~ 150 mass region are investigated systematically. Good results for the ?-ray energies, the dynamical moments of inertia, and energy differencesare obtained. It shows that this approach is quite powerful in describing not only the SD bands in even-even and odd-A nuclei but also those in odd-odd nuclei in the mass region.
