[en] The European Activation System (EASY) includes, as the source of nuclear data, the European Activation File (EAF). A new version of EAF, EAF-2001, has been developed, and this report gives details of the EAF decay data library. The sources of data and the methods of assembly are described, but the bulk of the report is devoted to a listing of summary properties of all the 1917 nuclides contained in the library. The summary properties listed are: nuclide spin, decay modes, half-life (with percentage error), mean decay energies and data source. (author)
