Abstract
The transport of electrons which undergo only elastic scattering has been studied by a method similar to the S{sub n} method in reactor physics. The electrons were assumed to have a normal incidence on the plane surface of a semi-infinite medium. The method was first tested for isotropic scattering. Good agreement was obtained with available analytical results for the albedo and for the reflected angular distribution. Calculations were then performed on aluminium and gold at 1 keV electron energy. The differential cross sections were taken in analytical form from the literature. It was found that at least 48 directional cosines are needed for good accuracy. The results for the albedo and the reflected angular distribution were compared to Monte Carlo calculations with very good agreement. Some efforts to obtain also the path length distribution were in vain, since the numerical method is not suitable for this purpose. 9 refs, 2 figs.
