✦ Synopsis

We present a complete calculation of the dynamical polarizability induced on an atom or a centrosymmetric molecule by the presence of a perfect metallic surface. This polarizability, which appears as a direct consequence of modifications by the surface of vacuum fluctuations is here calculated by using the stationary perturbation method. This method, not usually used in calculations of dynamical properties, appears to be more "economical".
