JEFF-4.0 Evaluated Data: thermal scattering law data

Evaluated data associated to JEFF-4.0 nuclear data library: thermal scattering law (TSL) sub-library.

The JEFF-4.0 sub-library for thermal-neutron scattering provides a comprehensive dataset including the thermal scattering data for the elements of 84 materials of which 24 are in elemental form and 60 are compounds. Special attention has been paid to key reactor materials, providing evaluations for U and O in UO2, Pu and O in PuO2, Th and O in ThO2, and Zircaloy (Zy4). The files in the JEFF-4.0 TSL sub-library are from different sources:

• 36 elements are from the JEFF project, with 16 files that are new compared to JEFF-3.3, updates in 6 files and a new evaluation for the important case of hydrogen in water (H in H2O).
• 31 elements from ENDF/B-VIII.1 library.
• 65 elements from the NJOY+NCrystal Library.
