Inelastic Interactions

An important part of condensed matter physics in recent years has involved detailed study of inelastic interactions between swift electrons and condensed matter surfaces. Here we will review some aspects of such interactions.Surface excitations have long been recognized as dominant in determining the exchange-correlation energy of charged particles outside the surface. Properties of surface and bulk polaritons, plasmons and optical phonons in plane-bounded and spherical systems will be discussed from the viewpoint of semiclassical and quantal dielectric theory. Plasmons at interfaces between dissimilar dielectrics and in superlattice configurations will also be considered.

Diffraction Effects

Recent investigations have shown that the inelastic scattering of electrons in gases exhibits some very interesting phenomena. In previous papas we have described the angular distribution of the scattering of electrons which have lost a discrete amount of energy. Papers I and II described preliminary results which established the existence of diffraction effects at large angles in a number of gases. In Paper III the measurements were carried out over a range of velocities lower than those previously studied, results being obtained for incident electron energies down to within a few volts of the excitation potential. angular distributions were obtained for the inelastic scattering of electrons in hydrogen, helium, and argon between the angles 10° and 155°. The present paper describes the extension of the measurements to methane, nitrogen, neon and mercury vapour.
