Abstract：
Identical bands of odd-A superdeformed nuclei in the A～190 mass region have been investigated using triaxial-particle-rotor model within the framework of the BCS pairing correlation. Three pairs of identical bands (¹⁹¹Au, ¹⁹¹Hg(b1)), (¹⁹¹Hg(b2),¹⁹³Hg(b2)), and (¹⁹¹Hg(b3), ¹⁹³Hg(b3)) are analyzed. It is pointed out that the identity in the γ-transition energies in these bands may be the result of the occupation of some special orbitals.
