摘要：

The Schrodinger equation for electron-hydrogen scattering is solved directly using finite-element analysis. Below the n = 2 threshold, accurate phase shifts for 0 less-than-or-equal-to L less-than-or-equal-to 3 are obtained and compared with variational and R-matrix results. Resonance positions and widths are also calculated and are in good agreement with other theoretical values. Above the n = 2 threshold, partial-wave contributions to the cross sections sigma1s-1s, sigma1s-2s, and sigma1s-2p are calculated and compared with those obtained using close-coupling and R-matrix methods. Wave functions are shown for both elastic and multichannel scattering.
