Paper Abstract

The absorption coefficient is calculated using the density-density response function (chi) (q(parallel),(omega) ;z,z'). The surface localized Tamm states yield an extra peak in the spectrum. The Coulomb interaction among the electrons shifts the resonant energy upward, changes the line shape, and leaves a weak but well-defined structure behind.
