Résumé

The Bragg reflectivity of a monocrystal of copper sulphate in the energy region around the K edge of copper is examined for an extended fine structure similar to EXAFS. A calculation based on a mode1 of a mosaic crystal shows that the structure is derived from the EXAFS as well as from an analogous effect in the scattering amplitude. The result can be brought to the same form as EXAFS, but with additional phase shifts. In an experimental comparison of the structure to the standard EXAFS of a thin copper sulphate plate the existence of phase shifts is confirmed.
