Abstract

A quantum-mechanical formulation of the dynamical self-consistent electrostatic interaction near metallic surfaces is developed for the case of planar, spherical and cylindrical solids, based on the use of symmetry decomposition of the problem. Analytic expressions are given for the response functions in the jellium Infinite Barrier Model in the Random Phase Approximation. The knowledge of the interaction propagator enables us to find and discuss various physical properties of the system, in particular the spectrum of elementary (single particle and collective) electronic excitations.
