Consistent description of magnetic dipole properties in transitional nuclei

Abstract

It is shown that a consistent description of magnetic dipole properties in transitional nuclei can be obtained in the interacting boson model-2 by the F-spin breaking mechanism, which is associated with differences between the proton and neutron deformations. In particular, the long standing anomalies observed in the g-factors of the Os-Pt isotopes are resolved by a proper inclusion of F-spin breaking without appeal to shape-coexistence or single-particle degrees of freedom.
