Abstract
The transport process of medium-energy secondary electrons in a metal is investigated on the assumption that they are scattered by a screening Coulomb potential. Scattering angles are selected which satisfy the relation E′ sin2 θ ≤ E0. In this case the integral equations for the expansion coefficients of the distribution function of the secondary electrons reduce to linear differential equations whose solution is carried out on a computer. The energy distribution of the outer secondary electrons is derived for the following two cases; 1) the mean free path ι (E) is constant; 2) ι (E) depends on the energy according to Ritchey and Ashley [6]. Comparison with experiment shows that the distribution of the secondary electrons is closer to the experimental one in the first case.
