Phys. Rev. C 64, 064320 (2001) [6 pages]Description of the identical superdeformed bands and ΔI=4 bifurcation in the A∼130 regionReceived 19 March 2001; published 21 November 2001 Within the supersymmetry scheme including many-body interactions, identical superdeformed (SD) bands and ΔI=4 bifurcation in A∼130 mass region are investigated systematically. Quantitatively good results for the γ-ray energy (Eγ) spectra, dynamical moments of inertia, and energy differences ΔEγ-ΔEγref are obtained. This shows that the supersymmetry approach is quite powerful in describing not only generic rotational properties, but also ΔI=4 bifurcation and identical SD bands simultaneously. Meanwhile, the ΔI=4 bifurcation may come from the perturbation with SO(5) [or SU(5)] symmetry on the rotational symmetry. © 2001 The American Physical Society URL:
