The Magnetic Moments ofAg107andAg109and the Hyperfine Structure Anomaly

The nuclear magnetic moments of ${\mathrm{Ag}}^{107}$ and ${\mathrm{Ag}}^{109}$ are measured by nuclear induction and found to be $\mu \left({\mathrm{Ag}}^{107}\right)=-(0.113042\mathrm{}\pm 0.000013)$ nm and $\mu \left({\mathrm{Ag}}^{109}\right)=(0.129955\mathrm{}\pm 0.000013)$ nm. The ratio of the moments is measured to be $\frac{\mu \left({\mathrm{Ag}}^{107}\right)}{\mu \left({\mathrm{Ag}}^{109}\right)}=0.86985\mathrm{}\pm 0.00001$; this ratio combined with the ratio of the hfs separations as measured by Wessel and Lew yields for the hfs anomaly $\Delta =-(0.412\mathrm{}\pm 0.006)$ percent, which is compared to calculated values.
