Studies of the N=90 region: The decay of 154Eu to 154Gd
Description
The decay of 154Eu → 154Gd has been studied by γ-ray singles and γ-γ coincidence spectroscopy using an array of 20 Compton-suppressed Ge detectors. The primary goal of the work was to confirm or refute a large number of questionable features in the decay scheme: the outcome is the removal of 8 levels from the previously adopted scheme, with the result that a new type of collective band is revealed. Many weak decay branches for the decay are clarified. These results are critical for understanding the structure of 154Gd and the N = 90 isotones; and the improved completeness of the decay scheme contributes to the use of 154Eu as a metrological standard
