Abstract
We apply the convergent close-coupling method to the calculation of electron scattering on the ground state of He+. It is shown that the inclusion of the treatment of the continuum, even below the ionization threshold, significantly reduces the calculated 2S cross section. We generally find good agreement with the measurements of the 2S excitation cross section, though in the vicinity of a few eV near threshold our results are characteristically higher than the experiment. Complete quantitative agreement is obtained with the measurement of the total ionization cross section from threshold to 700 eV.Keywords
