| It is well known that the shape of energy-loss spectra changes with specimen thickness due to plural inelastic scattering. Figure 957 shows carbon (C) EELS for t/λ varying from 0.05 to 1.45, calculated from the single scattering distribution based on Poisson Distribution. It clearly shows that the background increases nonlinearly as a function of t/λ corresponding to the multiple scattering terms. On the other hand, as t/λ increases, the shape of the spectrum changes due to the multiple scattering.
