Inelastic Scattering of Fast Particles by Plasmons
This article is divided into two main parts. In the first part the basic classical concepts of bulk and surface plasmons are reviewed for different surface geometries and model hamil-tonians are constructed for the description of the approximate independent boson behaviour of these collective electronic degrees of freedom and for their interaction with charged particle probes. In the second part, a number of applications in various plasmon spectroscopies will be studied. Only cases where the semi-classical, high-energy approximation holds will be examined.
Energy loss spectra of fast charged probes will be explained for both bulk transmission and for surface reflection geometries in terms of coherent excitation of plasmons. A recent method in which the particle probe is internally excited by scattering off plasmons will also be studied.
