A coupled-channel optical method for electron–atomic-hydrogen scattering is presented in a form that treats both the projectile and the target electrons symmetrically. Elastic differential cross sections are calculated at a range of energies from 0.5 to 30 eV and are found to be in complete agreement with the absolute measurements of Williams [J. Phys. B 8, 1683 (1975); 8, 2191 (1975)]. Total and total ionization cross sections are also presented.
