Van Hove correlation functions from coherent neutron inelastic scattering

Experimentally determined coherent dynamic scattering functions for liquid bismuth and Pb are used to derive the van Hove correlation functions G(r,t) and G sub s (r,t). It is demonstrated that it is possible to obtain direct and physically adequate information on the atomic self-motion from a neutr...

Summary:Experimentally determined coherent dynamic scattering functions for liquid bismuth and Pb are used to derive the van Hove correlation functions G(r,t) and G sub s (r,t). It is demonstrated that it is possible to obtain direct and physically adequate information on the atomic self-motion from a neutron inelastic scattering measurement on a completely coherent scatterer.
