Abstract
Theγ-γ directional correlations for cascades observed in the 4.1 hour149Tb decay were measured on the multidetector system consisting of 7 Ge (Li) detectors. The results together with the experimental data on the internal electron conversion allowed a model-independent assignment of the spin values at a confidence level higher than 95% for three levels in149Gd: 325 keV 3/2−, 817 keV 3/2− and 1206 keV 1/2−. Multipole mixing ratios for sixγ-transitions were also derived.
