Reconciliation of dispersion theory with experiment in anomalous x-ray scattering

Recent reports of conflict between atomic X-ray scattering factors as measured interferometrically and as calculated via dispersion theory are shown to arise from: (i) use of dispersion relations inappropriate to the incomplete absorption data presently available; and (ii) neglect of relativistic co...

Summary:Recent reports of conflict between atomic X-ray scattering factors as measured interferometrically and as calculated via dispersion theory are shown to arise from: (i) use of dispersion relations inappropriate to the incomplete absorption data presently available; and (ii) neglect of relativistic corrections to the Thomas scattering cross section.
