The activation data files provide the activation cross sections of neutron-induced nuclear reactions. The maximum incident energy is 20 MeV. The data consist of the production cross sections (MF3) of radioactive and stable nuclides and partial production cross sections (MF10) for the ground and isomer states of nuclides. The pointwise data were reconstructed from the resolved resonance parameters of the neutron sublibrary, and were made at temperatures of 293.6 K.
