WebThe diffraction on crystals, especially in the past, and currently on multilayer mirrors, are used below 1 keV. At higher energies, up to some tens of keV, the photoelectric effect is exploited nowadays, while Thomson scattering was previously used. The Compton scattering instead is exploited in the 100 keV energy range.
