Joint Evaluated Fission and Fusion (JEFF) Test libraries

The JEFF-4.0 library is currently in development and test sub-libraries are being prepared. To assist in the effort of testing these datasets, several evaluated and processed data libraries are provided to the public and are accessible from these pages.

Warning

These libraries are in development and have not been officially released. The latest official release remains JEFF-3.3.

Evolution of the library

The evolution spreadsheet is crucial for monitoring the library's content and its development:

  • Sheet 1: evolution of the JEFF library from JEFF-3.3 to the final release JEFF-4.0. It includes all the changes, isotope by isotope, from one version to the other. The comments are general.
  • Sheet 2: more detailed description of the changes, including links to the issue tracker on GitLab, the person responsible for the change, and the status of the file itself.
