Les Pertes d'Energie Caractèristiques des Electrons dans les Solides

B. Gauthe Paris: Gauthier–Villars. 1968 Pp. viii + 72. Price £2 2s. The main progress in the field of electron energy losses in solids in the last 10 years or so has been the discovery of the excitation of collective oscillations, both in the bulk and on the surface. This book reviews the interpretations that have been given of the electronic spectra of some metals, in terms of these two kinds of excitation, and their relation to the optical properties.
