Abstract：
The △I= 1 staggering is investigated for the superdeformed bands observed in the doubly odd nuclei ^150,152Tb,^144,148Eu and ^130,132Pr. The spin values of these bands are assigned from the ab-and modified ah-fitting. The possible mechanism and the inherent physics of the △I=1 staggering are outlined in the case of doubly odd nuclei.
