Influence of Thickness Fluctuations on the Energy-Loss Spectra of Protons Transmitted Through Thin Films
Structures appearing in the energy-loss spectra of energetic protons transmitted through thin Al films, such as peaks and shoulders, are studied as a function of both the bombarding energy and the tilt angle of the foil with respect to the beam direction. The results not only confirm previous evidences indicating that the foils contain thickness inhomogeneities, but also suggest that such inhomogeneities can be attributed to a discrete set of thicknesses.
