Abstract

The microscopic mechanism of the identical bands in odd-odd nucleus Tl-194 and its neighbor odd-A nuclei Tl-193,Tl-195 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 omega variation of the occupation probability of each cranked orbital and the contributions to moment of inertia from each cranked orbital are presented.
