Microscopic mechanism of identical superdeformed bands in 192,193,194Hg -: art. no. 024320

The microscopic mechanism of identical superdeformed bands in Hg-192,Hg-193,Hg-194 is investigated using the particle-number conserving treatment for the cranked shell model with monopole and quadrupole pairing interactions. In combination with the analysis for normally deformed identical bands in the rare-earth nuclei, it is shown that the identical bands observed in normally deformed rare-earth nuclei and superdeformed nuclei in the Asimilar to190 region result from the competition among shell effect, pairing interaction, blocking effect on pairing, and Coriolis antipairing interaction, where a strict and consistent treatment of blocking effect plays a crucial role.
