Abstract

Transient field precessions were measured for levels in the nuclides of^182,184,186W and¹⁹⁷Au as their ions simultaneously traversed polarized Fe and Gd hosts. Consistent sets of gyromagnetic ratios were inferred for the lowest 5/2⁺ and 7/2⁺ states in¹⁹⁷Au using these two ferromagnetic host media, provided that (i) the transient field for Au ions in Gd is calibrated using the W in Gd precessions (simultaneously measured) and, (ii) the transient field for Au in Fe is calibrated using the field strength and velocity dependence for Pt in Fe (previously measured). The present g-factor results are: g(5/2₁⁺;¹⁹⁷Au)=0.296±0.023, g(7/2₁⁺;¹⁹⁷Au)=0.241±0.021, and g(5/2₁⁺;¹⁹⁷Au)=1.2±0.2.
