Joint Evaluated Fission and Fusion (JEFF) Test libraries

The JEFF-4.0 library has been recently released after a thorough effort from the JEFF project. To assist in the effort of testing these datasets, several evaluated and processed data libraries were provided to the JEFF community and are accessible from these pages.

Warning

These libraries are test versions and have not been officially released. They led to the official release of JEFF-4.0 library.

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.
