DEFORMATION, PAIRING AND MAGNETIC-MOMENTS IN RARE-EARTH NUCLEI

The global behaviour of g-factors in the rare-earth region is examined . Magnetic moments of the 2(1)(+) states in even-even rare-earth nucle i with 60 less than or equal to Z less than or equal to 76 are calcula ted using the Migdal approximation for the moment of inertia. Attentio n is drawn to the implications of g-factors for the problem of identic al bands, particularly to the application of the concept of F-spin mul tiplets. The magnetic properties of the heavy, transitional nuclei are discussed in terms of the possibility that the proton and neutron dis tributions in these soft nuclei might have different deformations.
