摘要：

High-resolution electron-energy-loss spectroscopy has been employed to measure the dispersion of the surface plasmon on Ag(111) as a function of Cl coverage. The initial dispersion near q(parallel to)=0 is found to shift from positive at low Cl coverages to negative as the Cl coverage approaches one monolayer. This effect is explained qualitatively in terms of the positive charging of the Ag substrate and the plasmon screening caused by the Cl overlayer.
