Disparity in transient field characteristics for Au ions traversing Fe and Gd hosts through measurements ofg-factors in197Au

Abstract

Transient field precessions were measured for levels in the nuclides of 182'184'186W and 197Au 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 in 197Au 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,
