ELECTRON-ENERGY LOSS SPECTRUM OF TIN AT LOW PRIMARY BEAM ENERGIES

The electron energy loss spectra of clean and oxidised tin have been measured for primary energies in the range 100-1000 eV. The structure found for clean tin is similar to published spectra recorded with low primary energies except for the presence of a small peak at 4.7 eV. Differences between the reported volume plasmon energy recorded with low and high primary beam energies were noted and a model is presented to explain these differences in terms of plasmon dispersion. © 1979.
