Eikonal theory of intermediate-energy electron-atom scattering

An eikonal theory of elastic electron-atom scattering in the region of intermediate energies is proposed. In addition to the effects of the static and polarization potentials, we also take into account the leading absorption corrections, using the equivalent-potential method. Detailed calculations are performed for elastic electron-helium scattering in the energy range 100-500 eV. Our results are in good agreement with the recent experimental data. © 1971 The American Physical Society.SCOPUS: ar.j
