Joint Evaluated Fission and Fusion File
Also known as JEFF · JEFF Nuclear Data Library
The Joint Evaluated Fission and Fusion File (JEFF) project is a collaboration between NEA Data Bank member countries. The JEFF library combines the efforts of the JEFF and EFF/EAF Working Groups to produce a common sets of evaluated nuclear data, mainly for fission and fusion applications. It contains a number of different data types, including neutron and proton interaction data, radioactive decay data, fission yields, and thermal scattering law data
