Simple method for the simulation of multiple elastic scattering of electrons

Abstract

A screened Rutherford cross section is modified by means of a correction factor to obtain the proper transport cross section computed by partial-wave analysis. The correction factor is tabulated for electron energies in the range 0-100 keV and for elements in the range from Z=4 to 82. The modified screened Rutherford cross section is shown to be useful as an approximation for the simulation of plural and multiple scattering. Its performance and limitations are exemplified for electrons scattered in Al and Au.
