Abstract The large odd-even difference in moments of inertia between the SD bands l95Tl(l,2) and l96Pb(l) is investigated by the particle-number conserving method, in which the blocking effect on pairing is taken into account strictly. The ω variation of J(2) for the three SD bands are reproduced quite well and the underlying microscopic mechanism is demonstrated clearly. Calculations show that the blocking of the proton [642]5/2 intruder orbital and the excitation of [651]1/2 intruder orbital play crucial roles for the odd-even difference in J(2)’s.
