Anwendungsfelder des Führens mit Zielen are usually the outermost or valence electrons. If we now turn to x-ray spectra, we shah be concerned with the energy states of electrons in inner shehs. We shall see, however, that x-ray spectra can for the most part be treated as one-electron spectra, although they belong to many- electron atoms.
