Abstract：
The influence of the decoupling term in K=1/2 band on the extraction of the nuclear moments of inertia is investigated. The peculiar characters in the variation of the nuclear moments of inertia with spins are itemized for the K=1/2 band. On this basis three recently observed superdeformed bands in ¹⁹³T1 are discussed. An optimum explanation of the configuration structures is pro-posed to these bands. No sufficient evidence exists to conclude that all of them are of K=1/2.
