CSISRS alias EXFOR Nuclear reaction experimental data	Experimental nuclear reaction data for incident neutrons, charged particles, and photons. It covers more than 16,894 experiments and spans nearly all of neutron induced reactions experimental works.	Target Beam Product Nuclear reaction Energy Experimental method Authors Publication	Files containing nuclear reaction data such as cross sections, spectra, angular distributions, polarizations, etc, along with information on experimental technique, error analysis, and applied standards.
ENDF Evaluated Nuclear (reaction) Data File	Core nuclear reaction database containing evaluated (recommended) data from the ENDF/B-VII library (also JEFF, JENDL, ENDF/B-VI, BROND, and CENDL). It provides data in the ENDF-6 format, covering all nuclides of practical relevance (393 in total) for neutrons up to 20 MeV and partly up to 150 MeV. It serves as principal input for neutronics calculations, including nuclear reactor design, national security, accelerators, criticality safety, shielding, radiation protection and detector simulation.	Target Beam Product Nuclear reaction Energy Library	Files with reaction cross sections, particle and photon spectra, angular distributions, double-differential cross sections, fission yields and covariances (not all of these quantities are available for all materials); entire ENDF evaluation for a given material; comparison plots including experimental data.
