Computation of the total scattering cross sections for the halogens

Abstract

Calculated Total Cross-Sections (TCS) of elastic electron-atom scattering for F, Cl, Br, I and At are presented. The computed TCS were calculated using Born, Eikonal and the Optical Theorem approximation methods with the Lenz-Jensen potential, at electron incident energies between 1to1000 eV. Results obtained are in good agreement with experimental TCS data.
