Abstract
Abstract Strutinsky-type cranking calculations with inclusion of pairing correlations have been performed for the rare-earth nuclei 156, 158, 164Dy and 164Er. The pairing effects contribute significantly and with their inclusion the calculated yrast spectra agree very well with experiments. Using Hartree-Fock-Bogouliubov cranking wave functions we have calculated the magnetic moments and quadrupole moments for states up to spin I = 20 h . The quadrupole moments are found to be constant over the whole spin range. The gyromagnetic factors g(I) show a strong I-dependence for 156, l58Dy, a weaker one for 164Er and none for 164Dy. The sensitivity of this spin dependence on the single-particle occupation and the pairing degrees of freedom is studied. It is found that the spin variation of the gyrofactors is a rotational alignment effect.
