In the analytical technique of photoelectron spectroscopy (PES), a sample is ionized using high-energy radiation, and the kinetic energies of the ejected electrons (called photoelectrons) are measured. From this, we can determine the binding or ionization energy of each electron in the atom or molecule.

Nyckelord: Argon, Augers, Orbits, Photoelectron spectroscopy, Photoelectrons, Photons, Auger transitions, Configuration-interaction calculations, Core-hole

Photoelectron spectroscopy is based upon a single photon in/electron out process and from many viewpoints this underlying process is a much simpler phenomenon than the Auger process. The energy of a photon of all types of electromagnetic radiation is given by the Einstein relation : (5.3.1) E = h ν The full electron configuration of 6P is..
