IAEA Nuclear Data Section: Horizontal evaluations, 2003/05

The decay scheme data for a limited number of radionuclides have been evaluated during 2003-05, and incorporated into the European Activation File (EAF) for fusion studies. Similar studies have also been completed for the radionuclides within the Ra-226 decay chain, apart from Bi-214 which has proved to be problematic because of the relatively high degree of complexity of the decay scheme. All of the recommended decay data were tested for their consistency in terms of the completeness of the resulting decay scheme (expressed as % deviation between the effective Q-value determined from the branching ratios and component Q-values, and the calculated Q-value derived from all components of decay). Good to excellent consistencies have been obtained. (author)
