About EXFOR

The experimental nuclear reaction database, known as EXFOR stores nuclear reaction data and its' bibliographic information, as well as experimental information about the data. The status (e.g., the source of the data), and history (e.g., date of last update) of the data set is also included.

The data presently included in the EXFOR databases include:

• a "complete" compilation of experimental neutron-induced reaction data,
• a selected compilation of charged-particle-induced reaction data,
• a selected compilation of photon-induced reaction data.

The data is compiled in the EXFOR format, which was originally conceived for the exchange of neutron data, and was further developed and adapted to cover all nuclear reaction data. The format is designed for flexibility in order to meet the diverse needs of the nuclear reaction data centers, and allows a large variety of numerical data tables with explanatory and bibliographic information to be transmitted in a format:

• that is machine-readable (for checking and indicating possible errors);
• that can be read by personnel (for passing judgement on and correcting errors).

In addition to the EXFOR format, users may obtain data from the centers in other center-to-user formats that have been developed to meet the needs of users within each center's own sphere of responsibility.
