Incoherent scattering of x-rays

WebNov 10, 2024 · “In the case of X-rays, incoherent scattering usually predominates, for example when fluorescent light is produced by photon absorption followed by photon emission,” explains Anton Classen from FAU, who is the principal author of a recent paper in the journal Physical Review Letters where the method was first presented theoretically ... WebMay 1, 1990 · The coherent and incoherent scattering are basically treated as competing processes and being such, to a . first-order approximation, f + S = Z. The approach starts with the assumption that the cross sections depend on the photon energy and scattering angle only through the single parameter q.
