Identical superdeformed bands in Tl isotope

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