Abstract

They γ-ray spectra accompanying the β- decay of 160Tb to levels in 160Dy has been studied using Ge(Li) detectors. Coincidence measurements were made in order to separate unresolved transitions. Five reduced E2 transition probability ratios for transitions between the gamma and ground state band were computed from the measured γ-ray energies and intensities. The band mixing parameters deduced from each ratio are determined to be mutually inconsistent. The values, z2 × 103, are: 49.5±4.0, 18.7±2.8, 29.24±2.1, 30.5±4.7 and 55.8±5.6. A critical inconsistency with internal conversion data is pointed out. © 1970.
