Thermal Neutron Scattering Research and Development at Oak Ridge National Laboratory [Slides]
- Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)
This presentation provides an overview of the project, specifically describing how neutron cross sections can be broken up into several regions. It also discusses how thermal scattering law (TSL) $$\textit{S(α, β)}$$ is related to dynamic structure factor $$\textit{S(q, E)}$$ and how $$\textit{S(q, E)}$$ can be broken up into 2 primary components, incoherent and coherent, and how it can be calculated in several ways, including density functional theory (DFT) and molecular dynamics (MT). Additionally, it states that ENDF currently stores coherent elastic (Bragg edges), incoherent elastic and incoherent inelastic. Also discussed are the experimental capabilities, evaluations, and uncertainty quantification of the project.
