Abstract

A study of magnetic dipole strength in the rare-earth region and application to the 148–160Gd isotopes has been carried out. Within the Nilsson model, all two-quasiparticle Kπ=1+ configurations have been constructed and the M1 strength distribution has been calculated. Information on the total summed (non-energy-weighted) M1 strength is obtained. The distribution of orbital and spin M1 strength over different energy regions and over the whole rare-earth mass region was studied. Relations to quadrupole ground-state deformation are pointed out.
