For <sup>104<\/sup>Ag<sup>g<\/sup> (I<sup>&pi;<\/sup>=5<sup>+<\/sup>) the &gamma;-NMR\/ON resonance signal was found at &nu;=266.70(5) MHz. Combining this result with the known magnetic moment for this isotope, the magnetic hyperfine field of Ag impurities in an Fe host at low temperature (<1 K) is found to be |B<sub>hf<\/sub>(AgFe)|=44.709(35) T. A detailed analysis of other relevant data available in the literature yields three more values for this hyperfine field. Averaging all four values yields a new and precise value for the hyperfine field of Ag in Fe; that is, |B<sub>hf<\/sub>(AgFe)|=44.692(30) T. For <sup>104<\/sup>Ag<sup>m<\/sup> (I<sup>&pi;<\/sup>=2<sup>+<\/sup>), the anisotropy of the &beta; particles provided the NMR\/ON resonance signal at &nu;=627.7(4) MHz. Using the new value for the hyperfine field of Ag in Fe, this frequency corresponds to the magnetic moment &mu;(<sup>104m<\/sup>Ag)=+3.691(3) &mu;<sub>N<\/sub>, which is significantly more precise than previous results.
