Ground-state nucleargfactor ofRu97

The magnetic hyperfine splitting constant $\frac{g{\mu }_N{H}_{\mathrm{HF}}}{h}$ of ${}_{}{}^{97}{}_{}{}^{}\mathrm{Ru}$ as a dilute impurity in Fe has been determined by the technique of nuclear magnetic resonance on oriented nuclei to be 117.69±0.02 MHz. With the known hyperfine field for $\mathrm{Ru}\mathrm{Fe}$ of -504±12 kG the ground-state nuclear $g$ factor of ${}_{}{}^{97}{}_{}{}^{}\mathrm{Ru}$ is deduced to be (-)0.306±0.008. The resonance shift and the spin-lattice-relaxation time have been measured as functions of an external magnetic field.
