Abstract：
The counterpart which is related to the ΔI=4 bifurcation was separated properly from the observed transition energies. The spins of a superdeformed band may be assigned more accurately by the ab fitting after the ΔI= 4 bifurcation is removed. The spin assignment for the superdeformed bands in ¹⁹⁴Hg were re-investigated. A linear increasing is shown in the dynamic moments of inertia and the deflection disappears.
