SUMMARY A recently developed method based on matrix analysis for the removal of plural scattering from angle‐resolved energy loss spectra is tested. A single loss function, Lorentzian in the energy and Gaussian in the angular variable is assumed as input for the test. Multiple scattering probabilities are simulated by summing up n ‐fold self‐convolutions of the input function according to the Poisson distribution for incoherent n ‐fold scattering. The simulated profile serves as input for the retrieval algorithm, the result of which is compared with the original single‐loss probability. It is concluded that the method is feasible, but not likely to be suited for routine investigations.
