Abstract

Monte Carlo approach has been frequently used to provide reliable parameters characterising the elastically backscattered electrons. In the present work, the Monte Carlo algorithms developed by Jablonski and that by Gruzza and co-workers, used in studies of electron interaction with solid, were compared. The energy dependence of electron elastic-backscattered intensity for cylindrical mirror analyser (CMA) were calculated for Ag and Ni using these two algorithms and compared to the measured data in the 50–2000 eV energy range. It appears the first algorithm gives the same maxima and minima as the second. The experiment confirms, in the investigated energy range, existence of two maxima, at about 200 and 1200 eV, one minimum, at about 500 eV for Ag and one maximum at about 400 eV for Ni in the energy dependence of the intensity of electrons elastically reflected from the studied samples for the CMA configuration.
