Abstract
The dependence of the surface plasmon peak intensity on a submonolayer coverage of oxygen in the reflection electron energy loss spectra has been investigated for non-monocrystalline aluminium, magnesium, and i ndium surfaces. It will be shown that the decrease of the surface plas mon peaks can be related to a modification of the surface plasmons dis persion relation. A simple model for this modification introduced by c hanges of the surface electron density profile is proposed. Parameters of this model will be determined from experimental data.
