EXCITATION OF SURFACE PLASMA WAVES BY A CHARGE MOVING PARALLEL TO THE METAL-VACUUM INTERFACE,
Abstract
Research into the excitation of surface waves by a changed particle incident on a metal vacuum interface or into the radiation generated by the motion of the particle parallel to this interface can provide important information on the structure of the energy spectrum of the electron Fermi-fluid in metals. In this connection the theory of the radiation generated by the motion of a charge parallel to the metal-vacuum interface with an arbitrary law of electron variance is considered for a particle with the charge q moving in a vacuum with the velocity v parallel to the plane surface of a crystal occupying the half-space z < O, along the trajectory x = vt, y = o, z = a (the oz-axis is directed along the outer normal to the surface). The expenditures of charge energy per unit path on the excitation of surface waves are determined for the case where the optical axis of the uniaxial crystal is at right angles to the interface, since then the electron Fermi-fluid can be described with the aid of the permittivity tensor.
