Abstract

The gyromagnetic ratios of the 2₂⁺ and 4₁⁺ states in ¹⁹²Os were measured relative to that of the 2₁⁺ level. The thin foil, perturbed γ-ray angular distribution technique was employed utilizing the transient hyperfine magnetic field present at the nuclei of these ions as they swiftly recoiled through a thin, magnetized Co foil. The states of interest were Coulomb excited using a beam of 220 MeV ⁵⁸Ni ions. The present measurements yielded ratios g(2₂⁺) g(2₁⁺) = 0.68 ± 0.08 and g(4₁⁺) g(2₁⁺) = 1.00 ± 0.12. The sizable disparity in the measured g-factors of the levels of the two low-lying bands is compared with interacting boson approximation model-based calculations, as well as with a Nilsson basis single-particle model description.
