Using Monte Carlo simulations, the mean energies of backscattered electrons for thick targets of aluminium, titanium, iron, molybdenum, tungsten and lead were calculated at various angles of incidence and an incident electron energy E 0 of 30 keV. The results show that the mean energy ratio, Ē B / E 0 , of backscattered electrons depends only on the backscattering coefficient, η B , of the non‐normal electron incidence and varies linearly with it. Analytical expressions are given for calculating Ē B / E 0 and the backscattering coefficient, which is independent of the backscattering coefficient at normal incidence.
