Dynamical Image Charge Interactionse (low energy electron diffraction, fast electron spectroscopy, etc.) or the ejection of charged particles from the surface (photoemission, field emission). These dynamical interactions are dependent on the nature of the elementary excitations at the surface.

Inelastic X-Ray Scattering from Electrons in Mattertc). X-rays are in a real sense the high-frequency limit of visible light. They extend manyfold the range of frequencies and wavelength one can hope to examine. They have energies in the 10 kilovolt range with wavevectors in the 10. cm. range. They couple primarily to charge and to light masses (i.e. electrons).

Effects of Exchange and Correlation in the Electron Bandstructure Problem have further written the electron-electron interaction on the form ρ.ρ. which differs from the correct expression . by the (infinite) constant .. Those who objects to infinite constants may flatten the Coulomb potential for .< .. which gives a convergence factor sin(..)/... In the final expressions we can then take .. → 0.
