Identical Bands and Alignment in ^193,194Tl

The microscopic mechanism of the identical bands in odd-odd nucleus ¹⁹⁴Tl and its neighbour odd-A nucleus ¹⁹³Tl are investigated using the particle-number conserving method with monopole and quadrupole pairing interaction. It is found that the blocking effect plays an important role in the variation of moments of inertia (J⁽¹⁾ and J⁽²⁾) with rotational frequency for the superdeformed bands and identical bands. The alignment of ¹⁹⁴Tl bands with respect to the ¹⁹³Tl(1) band used as a reference is also discussed.
