Abstract

The gyromagnetic ratios $g$ of the 122-keV state of ${Sm}^{152}$ , of the 123-keV state of ${Gd}^{154}$ , and of the 89-keV state of ${Gd}^{156}$ have been measured to be 0.35±0.03, 0.367±0.03, and 0.32±0.03, respectively, by the precession of the angular correlation of gamma-ray cascades proceeding through these states in an external magnetic field. The perturbations of the angular correlations for sources both in aqueous solution and in molten anhydrous chlorides have been studied. The attenuation in a transverse magnetic field was used to determine the hyperfine structure constant of the 89-keV state of ${Gd}^{156}$ in the ${}^{8}S_{\frac{7}{2}}$ ground state of ${Gd}^{3 +}$ in aqueous solution as $a = 17 \pm 3$ Mc/sec. The perturbations in molten Gd sources were found to be much weaker than in solution and to be unaffected by magnetic fields.
