Abstract
The particle-number conserving (PNC) method for treating the cranked shell model with monopole and quadrupole pairing correlations is used to study the superdeformed (SD) bands observed in odd-odd nuclei in the Aâ¼190 mass region. Spins are assigned to the levels in these bands. The microscopic mechanism of the âÏ evolution of the dynamic moment of inertia J(2) for these SD bands are analyzed. In particular, the major roles of the j15/2 neutron and i13/2 proton orbitals played in the SD bands are investigated in detail by contributions to J(2) from each cranked orbital and interference terms between two cranked orbitals. Additivity in the Aâ¼190 mass region is investigated. The experimental evidence for additivity of alignments in 192Tl can be reproduced by our calculations.
