Abstract
An operator expansion of the matrix is shown to lead to an equation for describing charge polarization on elastic scattering similar to that reported previously by use of the infinite-channel close-coupling approximation in the second Born approximation. The resulting equations are used to calculate the charge-polarization corrections for elastic electron scattering from H and He at incident electron energies of 100 eV, 500 eV, and 40 keV over the angular range of 0° to 50°. The results agree well with those of Bromberg and LaBahn and Callaway for elastic scattering from He with an incident electron energy of 500 eV.
