Nuclear Reaction Data

Evaluated data sets are produced through the process of critical comparison, selection renormalization and averaging of the available experimental data, normally complemented by nuclear model calculations.

Evaluated libraries are files of evaluated data which, appropriately processed, form the input data to computations for a wide variety of nuclear science and technology applications. Each of these evaluated libraries may consist of individual evaluated data sets for several hundred isotopes or elements. An index with descriptions of available evaluated nuclear data general and special purpose libraries is found on the link below:
Index of evaluated nuclear data libraries (updated April 2008)

More information

EXFOR is the name given to the database containing experimental reaction data. In addition to storing the data and it's bibliographic information, experimental information, including source of uncertainties, is also compiled.

The data presently included in the EXFOR database 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
  

More information

Bibliographic reaction data are entered into the CINDA database.

Nuclear Structure Data

Nuclear structure data refer to the properties of single nuclei, as opposed to reaction data which deals with the properties of a nucleus interacting with radiation or another nucleus.

Numerical data related to nuclear structure are available in the ENSDF and NUDAT databases.

More information

Bibliographic information on nuclear structure is found in the NSR database. The experimental and evaluated information stored in the numerical databases, such as NUDAT and ENSDF, have been compiled on the basis of the result of experiments and reviews published in a variety of scientific journals and reports. The bibliographic databases contain cross references between the information stored in the numerical databases and the original articles on which these data are based.
