Abstract
The authors compare two recently proposed ab initio optical model methods and obtain an improved absorption potential for the case of scattering of fast charged particles by heavy atoms. Detailed calculations are performed for elastic scattering of electrons and positrons by argon in the energy region 100 eV-1 keV. The differential cross sections for electron scattering are in excellent agreement with recent absolute measurements. Total cross sections for both electron and positron collisions are also discussed.Keywords
