Improved Theoretical X-Ray Resonent Scattering Amplitudes
Resonant elastic scattering amplitudes f =f' +if" in the vicinity of the absorption edges have been obtained by applying a differential Kramers-Kronig transform to theoretical absorption code FEFF. By including solid-state effects due to the local environment of a resonant atom, FEFF makes significant improvements to existing calculations of the resonant scattering amplitudes. The results are compared to experimental measurements of Bragg peak intensities as a continuous function of energy for Cu metal and Yba(2)Cu(3)O(6.8) at the Cu K absorption edge, and for UO(2) at the U M(iv) absorption edge.
