Supersurface electron scattering, i.e. electron energy losses and associated deflections in vacuum above the<br />
surface, was investigated by Monte Carlo simulation in reflection electron energy-loss (REELS) setup. These<br />
theoretical calculations predicted a strong structure in the detected supersurface inelastic scattering probability<br />
that was proven by experiments in case of Au sample leading to the unambiguous identification of the vacuum<br />
side electron scattering in reflection experiments [1]. These deflections, in vacuum side surface plasmon<br />
excitations, can establish a link between the detected vacuum side surface loss intensities and the differential<br />
elastic scattering cross section (DECS) resulting in the observable structure. The details and consequences of<br />
this supersurface electron scattering will be presented together with a Monte Carlo simulation study on the<br />
energy, geometry and material dependence of these complex phenomena.<br />
