g factors and the interplay of collective and single-particle degrees of freedom in superdeformed mass-190 nuclei - art. no. 047306

Interplay of collective and single-particle degrees of freedom is a common phenomenon in strongly correlated many-body systems. Despite many successfu l efforts in the study of superdeformed nuclei, there is still unexplored p hysics that can be best understood only through the nuclear magnetic proper ties. We point out that study of the gyromagnetic factor (g factor) may ope n a unique opportunity for understanding superdeformed structure. Our calcu lations suggest that investigation of the g-factor dependence on spin and p article number can provide important information on single-particle structu re and its interplay with collective motion in the superdeformed mass-190 n uclei. Modern experimental techniques combined with the new generation of s ensitive detectors should be capable of testing our predictions.
