Abstract
Transient field precessions were measured for levels in the nuclides of182,184,186W 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 presentg-factor results are: g(5/2 +1 ;197Au)=0.296±0.023, g(7/2 +1 ;197Au)=0.241±0.021, and g(5/2 +1 ;197Au)=1.2±0.2.
