Theoretical Verification of Thermal Neutrons Scattering

Abstract

One of the technologically most important interactions of neutrons with matter is their loss of energy (“slowing down”) by a series of elastic collisions. These can be treated by the methods of classical mechanics, assuming the interacting particles as perfectly elastic spheres. The energy loss is an important subject, and is discussed in several books where numerical tables and graphs are presented. Formulas are found semi empirically with several correction coefficients. Despite all efforts, no direct, exact formula has so far been obtained analytically. The purpose of this research is theoretical verification of thermal neutrons scattering by using a recently introduced method of the quantization of neoconservative systems and detailed comparisons with a significant number of measurements of differential and integral neutron cross sections and other relevant data are reported (for the validation of the generated Scattering Law data files S(α, β, Τ)), as ENDF data library are reproduced reasonably well, necessary in generating and processing the thermal neutron scattering data.
