Abstract
The reduced IERM approach is applied to electron scattering from hydrogen atoms to obtain accurate integrated cross sections for n = 1 to n = 3 transitions at intermediate energies. The results are in good agreement with recent coupled pseudostate calculations and with experiment but show that earlier work including 15 bound states in a close coupling expansion considerably overestimates these cross sections.Keywords
