Abstract

The gyromagnetic ratios of levels up to the 101+ in the ground-state band and of the 22+ state in the γ-band of166Er were simultaneously determined experimentally by means of the thin-foil, perturbed γ-ray angular distribution technique utilizing the transient hyperfine field manifest at nuclei of Er ions rapidly traversing polarized Fe. Beams of 220- and 160-MeV58Ni projectiles were used to Coulomb excite the levels of interest. The present results are compared with the spin-dependencies of g-factors of levels in the ground-band predicted by recent cranked Hartree-Fock-Bogoliubov calculations and with interacting boson model expectations which include g-boson effects.
