The European Activation File (EAF) is the collection of nuclear data that is required to carry out inventory calculations of materials that have been activated following exposure to neutrons. One of the components of EAF is the collection of neutron-induced cross section data.
The current release of the European Activation File, EAF-99, contains cross section data of neutron-induced reactions for energies between 10-5 eV and 20 MeV.
EAF-99 contains data for 98 elements from H to Fm, but excludes data for the short-lived radioactive elements At and Fr. There are a total of 766 traget isotopes, including ground, first and second isomers, which have non-zero cross sections (i.e. greater than 10-8 b) below an energy of 20 MeV. Cross sections to and from isomeric states are listed separately in a pointwise ENDF File 3 section format. This leads to a total of 12,468 reaction channels that contain data.
