The JEFF-4T1 nuclear data library content has been agreed upon in February 2022. It includes two sets of data containing 562 and 2813 neutron cross section evaluations, respectively.
Please note that this is a TEST library, and that the latest official release remains JEFF-3.3.
The first set, as the previous versions of JEFF, includes the 562 most important isotopes for criticality calculations. The content of the library can be found here: JEFF-4T1 Starter File. The second one includes the 562 isotopes of the previous set, but it is completed by the additional 2251 isotopes provided by TENDL-2021. This set is recommended for more general purposes.
The Thermal Scattering Law set includes 24 files, 19 of which are taken from JEFF-3.3. New evaluations are provided for H(H20), PuO2, and UO2. O(H2O) is taken from JENDL-5, while H(Lucite) is taken from ENDF/B-VIII.O. The TSL content in listed in the JEFF-4T1 Starter File.
