| Zusammenfassung | The interaction between photons and matter is one of the most fundamental processes. The interaction mechanism is well understood in the usual case of nonrelativistic photon energies and nonexcessive intensities. Studies of photon absorption and photon-induced processes thus provide a powerful tool to investigate properties of atoms, molecules, condensed matter, and surfaces. For example, cross sections for photon absorption probe the wave function overlap of electronic states; spectroscopy of absorbed or emitted radiation makes it possible to determine energy and width of levels. Atomic levels span an energy range of a few eV up to about 100 keV. Therefore, experimental studies have to employ photons in a correspondingly broad energy range. Feasibility and quality of experimental photoab-sorption and photon-induced emission studies are governed by the available photon sources and related instruments, which are quite different in the various ranges of photon energies. |
