Abstract：
the microscopic mechanism of the identical bands in odd-odd nucleus ¹⁹⁴Tl and its neighbor odd-A nucleus ¹⁹³Tl are investigated using the particle–number conserving (PNC) method with monopole and quadrupole pairing interaction. It is found that the blocking effect plays an important role in the variation in moments of inertia (J⁽¹⁾ and J⁽²⁾) with rotational frequency for the sd bands and identical bands. And the angular momentum alignment i(ω) of the six SD bands in ¹⁹⁴Tl relative to the ^{193^{Tl(1) also is discussed.}}
