Abstract

We present an analysis of electron incident angle-dependent reflected electron energy loss spectroscopy spectra of silver by using a Monte Carlo simulation method with which the separated contributions from surface and bulk excitations can be identified. The simulations were performed at several different incident electron energies and with various incident angles with respect to the surface normal. We found that the surface plasmon excitation plays a dominant role in the loss peak at around 3.7 and 7.5 eV.
