DOIAbstract
The omega variation of moments of inertia of superdeformed bands is investigated by a particle-number conserving (PNC) method of the cranked shell model Hamiltonian with monopole and quadrupole pairings. The observed omega dependence of the moments of inertia for Hg-192,Hg-194(1), particularly the shift in J((2)) downturn for Hg-194(1) to a higher frequency, are well reproduced by the PNC calculation. The microscopic mechanism of the omega dependence of J((2)) (contribution to J((2)) from each cranked Nilsson orbital) is clearly exhibited in the PNC calculation. The shift of the J((2)) downturn for Hg-194(1) is mainly attributed to the protons in the N = 6 intruder orbitals under the influence of Q(20) quadrupole pairing.http://gateway.webo...
