Abstract
Elastic electron-hydrogen scattering at intermediate energies is analyzed with a modified Glauber amplitude proposed earlier by this author and the Glauber exchange effect included through a recent eikonal formula by Foster and Williamson. The results of the calculation are found to be in very good agreement with experimental data. This work, therefore, confirms rather clearly that the deficiency of the Glauber amplitude when applied to these atomic processes, stems mainly from the inadequacy of the second-order term of its eikonal expansion in representing the second-Born term and that the Glauber exchange effect is of a considerable magnitude and, hence, cannot be neglected in these processes, especially at very large scattering angles.
