Collective gyromagnetic ratios g{sub R}, microscopically calculated from Hartree-Fock plus BCS calculations using the SkM{sup {asterisk}} force, are found to be very different from the rough Z/A estimates. It is pointed out that the latter disagree with the spectroscopic data in normally deformed states of even-even nuclei. The consequences of taking into account microscopic values of g{sub R} on the spectroscopic properties of odd superdeformed A=190 nuclei are discussed. Quenching factors, for proton and neutron g{sub s} ratios, are tentatively proposed. Single-particle assignments postulated by experimentalists for the available data are confirmed by our consistent approach. {copyright} {ital 1997} {ital The American Physical Society}
