Abstract
The statistical perturbations of γγ-angular correlations involving the first 2+ rotational state of154Gd and156Gd have been time differentially investigated. We used liquid sources of 3+ ions of Gadolinium in lN perchloric acid, 0.5 N and 1N hydrochloric acid, 1.3N and 2.6 N sulfuric acid. Influences of the various chemical surroundings on the ratio λ4/λ2 of the attenuation parameters have been found. A simultaneous measurement of the angular correlation of the 874 keV–123 keV cascade and the 2,098 keV–89 keV cascade of154Gd and156Gd, respectively, has been performed in perchloric solution. From the ratio of the attenuation parameters λ2, obtained by this experiment, we have derived the ratio of the magneticg-factors of the first 2+ levels of these isotopes asg 154/g 156=1.11±0.08.
