Many aspects of the interaction of charged particles with matter can be expressed in terms of the dielectric function . The dielectric function is relatively well known in the optical limit () but, for example, stopping power calculations require the knowledge of the dielectric function for . Several approaches have been used to extend the dielectric function to for both the valence electrons, using variations of the Lindhard dielectric function and the core levels where an atomic description...[Show more]
