Abstract：
The identical superdeformed bands of odd-A nuclei in the A ~190 mass region have been investigated by using the triaxial-particle-rotor model within the framework of the BCS pairing correlation. Three pairs of identical bands-(^19lAu, ¹⁹¹Hg(bl)), (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.
