Sažetak

In previous article we investigated collective oscillations in bilayer films. In the present paper we apply those results to electron energy Ioss spectroscopy for electrons reflected from and transmitted through a bilayer system. In studying electron reflection, we emphasize surface mode excitation, especially the influence of the substrate on the electron energy Ioss (EEL) spectrum. In analyzing electron transmission, we pay special attention to bulk mode excitation and to the discrete nature of bulk modes in thin films. We compare the theoretical results obtained for reflection and transmission EEL spectra with some experimental data and we find that the agreement is good.
