Differential Scattering Cross Sections for Elastic Electron-Magnesium Scattering

摘要

In the present work, theoretical studies of differential cross sections (DCS) of electron scattering by the Mg atom have been carried out at projectile energies of 10, 20 and 40 eV. The only experimental parameters required are the first ionization potential and the dipole polarizability of the atom under consideration for the construction of the full optical potential. After generating the full optical potential of the scattering system, we treat it exactly in a partial wave analysis in terms of a set of first-order coupled differential equations for the real and imaginary parts of the complex phase shift functions under the variable phase approach. The calculated DCS are compared with the experimental data and theoretical values.
