Experimental Nuclear Reaction Data

The EXFOR library contains an extensive compilation of experimental nuclear reaction data. Neutron reactions have been compiled systematically since the discovery of the neutron, while charged particle and photon reactions have been covered less extensively. The library contains data from more than 15,000 experiments.

IAEA Nuclear Data Section is collecting experimental nuclear physics data (numerical tables with experimental description) from laboratory reports, journal articles and unpublished literature for inclusion in EXFOR.

Transmission files are received from co-operating centres of the international network of reaction data centres (NRDC)and are added to database after quality control at IAEA.

Quality LevelExplanation of Terms

• Authoritative: All information in the resource has been verified by authorities as indicated.
• Quality-checked: All information in the resource has been quality-checked as indicated.
• Not quality-checked: Although the information in the resource may come from peer-reviewed journals or other high-quality sources, it has not undergone subsequent quality checking before incorporation in the resource.

: Quality-checked by Nuclear Reaction Data network Evaluated data
CompletenessExplanation of Terms

• Comprehensive:The resource includes all items in the category for which the resource was created.
• Selective: The resource includes only selected items in the category for which the resource was created, with the process or basis for the selection as indicated.

: Comprehensive
Update FrequencyExplanation of Terms

• Updated continually: A conscientious effort is made to add new information immediately and keep the resource up-to-date on a day-by-day basis.
• Updated periodically: The resource is updated on a schedule. Common values are monthly, quarterly, annually or biennially, but others are also used.
• Updated occasionally: The resource is updated now and then, but not on a schedule.
• Static: The resource is a one-off creation with no plans for updates, or a resource that was updated in the past but has now been frozen with no new input planned.
