Abstract

A noniterative-integral-equation method (NIEM) is successfully applied to S-wave scattering of electrons by atomic hydrogen. Reactance-matrix elements and partial-wave cross sections are computed for energies above and below the n=2 threshold. The results are stable despite the strong degenerate dipole coupling between the 2s and 2p channels. In addition, it is demonstrated, by locating the first S1 resonance, that the NIEM works in the resonance region below threshold.
