Abstract
The measured dielectric constants ε1 and ε2 for the simple metals are incorporated into the theoretical equation for the surface response function, which is derived from a calculation based upon a “jellium” metal. This procedure gives a first order estimation of the effect of the bulk band structure upon the energy, dissipation and dispersion of the surface modes, such as the surface plasmon and the multipole mode. When ε2 is relatively small, the only noticeable effect is the increased damping for the surface plasmon for small q‖.
