Abstract
In this study the distorted wave method was applied in calculation of the differential cross sections (DCS) for elastic scattering of electron by a calcium atom at electron impact energies of 10, 15, 20, and 40 eV. At lower incident energies, 10, 15, and 20 eV the present DCS results are not in good agreement with other theoretical and experimental results. However, at 40 eV the present DCS results are in good agreement with other theoretical and experimental results. Key words : Cross-sections, distortion potential, distorted wave, static potential and spherical harmonics. DOI : 10.7176/APTA/83-09 Publication date: September 29 th 2020
