Nuclear Magnetic Moment, Hyperfine Structure, and Hyperfine-Structure Anomaly ofAg110m

The atomic-beam magnetic-resonance technique was used to measure the free-atom ground-state hyperfine structure separation $\Delta \nu$, the nuclear magnetic moment ${\mu }_I$, and the hyperfine-structure anomaly ${}_{}{}^{109}{}_{}{}^{}\Delta _{}^{110m}{}_{}{}^{}$ of 260-day ${\mathrm{Ag}}^{110m}\mathrm{}(I=6\mathrm{})\mathrm{}$. The magnetic moment ${\mu }_I$ was obtained independently of $\Delta \nu$ by observing a $\Delta F=\pm 1$ doublet at its field-independent point. The results are $\Delta \nu \left({\mathrm{Ag}}^{110m}\right)=+30313.756\mathrm{}\left(4\right)\mathrm{}$ MHz, ${\mu }_I\left({\mathrm{Ag}}^{110m}\right)\left(\mathrm{uncorr}\right)=+3.587\mathrm{}\left(4\right)\mathrm{}$ nm, and ${}_{}{}^{109}{}_{}{}^{}\Delta _{}^{110m}{}_{}{}^{}=-2.47\mathrm{}\left(12\right)\%$. The results are shown to fit in well with existing theories.
