Abstract
Elastic scattering of electrons by hydrogen atoms has been investigated in the plane wave approximation in 50-200 eV energy range. A general expression has been derived for the non-adiabatic potential in a Hermitian form. First-order perturbed wavefunctions and pseudo-states are employed to construct dynamic polarization potentials. The theory underestimates the differential cross sections, but the shapes of the theoretical curves are in agreement with the experimental data. The results are also in fair agreement with more sophisticated calculations.Keywords
