### Abstract

The IMFP of electrons in high atomic number solids was determined using elastic peak electron spectroscopy. The Monte Carlo calculations based on the differential elastic scattering cross-sections resulting from the partial wave expansion method made possible the accurate analysis of experimental results. Multiple elastic scattering of electrons is playing a dominant role in high atomic number elements. Experiments provided the ratio of elastic peak intensities for a given sample and the standard. The CMA was used in the measurements. In this work the IMFP of Ta, W and Au was studied, using Al as a standard. Multiple elastic backscattering probability. The ration of angular distribution of elastically backscattered electrons and the elastic backscattering probability. The ratio of elastic peak intensity of the sample and of the standard was calculated for the CMA detecting angle (θ = 138°) and fitted to the experimental results. Such procedure provides the true value of the IMFP. Results were obtained in the energy range between 500 and 3000 eV. They are compared to the available literature data.
