Abstract By using various approaches to the spin assignment, including the best-fit-method, the variation of moment of inertia with angular momentum, the bandhead moment of inertia J₀ systematics, and the signature systematics, the spin of the lowest level observed in the first discovered superdeformed band ¹⁵²Dy(1)is definitely predicted to be I₀ = 26(E_γ(I₀ + 2 → I₀) = 602.4 keV), rather than the previously predicted I₀ = 22,24, or 25. The spin prediction and properties of some superdeformed bands in the A ~ 150 region are discussed.
