| Abstract: | The microscopic mechanism of the identical bands in odd-odd nucleus 194Tl and its neighbor odd-A nuclei 193,195Tl is investigated using the particle-number-conserving (PNC) method for treating the cranked shell model with monopole and quadrupole pairing interactions. It is found that the blocking effect of the high-j intruder orbital 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  variation of the occupation probability of each cranked orbital and the contributions to moment of inertia from each cranked orbital are presented. |
