Transient fields for Ag and Pd ions IN Fe and Co;g-Factor measurements of the lowest 3/2^- and 5/2^- states in^107,109 Ag

Abstract

Transient field precessions of the 2+1 state of108Pd were measured simultaneously with those of the 3/2-1 and 5/2-1 states of107Ag and109Ag as their ions traversed thin Co and Fe foils. Precessions of the 2+1 states of104,106,108,110Pd were also measured using a natural Pd target evaporated onto 0.9 Μm thick Co. The results of these studies are in accord with prior predictions that the Ag Fe transient field might be diminished relative to that for Pd Fe at ion velocities appropriate for molecular orbital vacancy sharing. Transient field strengths for Pd Co and Pd Fe were found to be consistent with scaling according to bulk magnetization of the ferromagnetic host. Gyromagnetic ratios were inferred for the first 3/2- and 5/2- states of107,109Ag relative to the g factor of the 2+1 state of108Pd. Values obtained using g(2+1;108Pd)=0.36± 0.03 are:g(3/2;107Ag) =0.63±0.09, g(5/2;107Ag)=0.37±0.06, g(3/2;109Ag)=0.77 ±0.10, g(5/2;109Ag)=0.36±0.05.
