Abstract:
Based on the coherent elastic scattering, incoherent elastic scattering, coherent inelastic scattering and incoherent inelastic scattering, a code named SIRIUS is developed to generate the thermal neutron scattering data in ENDF-6 format for solid moderators, and the ab-initio calculation is used to calculate the phonon densities of states for the these solids. The TSL data for the metal
27Al as a FCC structure are generated by SIRIUS code, and are consistent with the data from ENDF/B-VII.1 library, which validate the correctness of the SIRIUS code.
