Abstract
A six state coupled-channel optical potential method for electron-atom scattering is applied to electron-hydrogen scattering at energies of 13.87, 16.46, 19.58, 35, 40, 54.4, 100, and 200 eV. The n = 1, 2, and 3 channels are coupled explicitly whereas the rest of the excited states of the atom including the continuum are taken into account via the `ab initio` complex non-local polarization potential. The differential and integrated cross sections, as well as the exchange asymmetries for n = 1 and 2 channels, the total cross section, and the {lambda}, R and I parameters for the 2p excitation are presented at each energy. The ratio of differential cross sections for n = 1 to n = 2, and for 2s to 2p, and the 2s + 2p differential cross sections are found to be in good agreement with experiment. There are still some discrepancies between experiment and theory for the 2p angular correlation parameters {lambda}, R and I. 24 refs., 9 tabs., 6 figs.
