On Plasmon Dispersion Measurements by EELS
The surface excitation spectrum of clean silver single crystal surfaces has been studied recently by angle resolved high resolution electron energy loss spectroscopy.
Some experimental aspects are elucidated with emphasis on the possible artifacts connected to the shape of the inelastic cross section or to elastic reflectivity variations which can complicate the interpretation of the data in this kind of measurement. Results will be presented for Ag(00l).
