Joint Evaluated Fission and Fusion (JEFF) Library version 3.3

JEFF-3.3 is a thorough update of the neutron, decay data, fission yields, dpa and neutron activation libraries in the EAF format, with neutron thermal scattering files for 20 compounds. Special sub-libraries for incident alphas, deuterons, gammas, helium-3, protons and tritons have been contributed by the TENDL-2017 library and adopted as part of the JEFF-3.3 release. JEFF-3.3 was officially released on November 20, 2017.

Latest official release

The JEFF-3.3 library is the latest official release from the JEFF project.

The JEFF community is continuing to develop a modern, general-purpose nuclear data library as part of the JEFF-4 project. No official release for JEFF-4 has been made and all versions are test libraries undergoing rigorous study by the experts involved in the project. JEFF-3.3 is the latest version released for use by the general public.

Downloads

The complete set of data, including incident-neutron files for 562 nuclides, processed ACE format data in several temperatures from 293K to 1800K, TSL data, multigroup cross sections, decay data, fission yields, incident data for alphas, deuterons, gamma, helions, and protons, and checking code outputs are available online here:
