An angular scattering effect of electrons in solids is taken into account in the previous Monte‐Carlo simulation model which has employed the modified Blunck and Leisegang (MBL) energy straggling distribution. The Mott cross‐section of elastic scattering is adopted for angular scattering. The electron trajectory consists of two kinds of steps; one is an elastic scattering mean free path as used in the conventional single scattering model, and the other is a step length defined using the MBL distribution in the previous paper. This simulation is applied to calculate several physical quantities such as backscattering and transmission coefficients, energy deposition etc. The calculated results are verified by comparing with the experimental data.
