摘要：

The present study incorporates the nonlocal optical potentials for the continuum within the coupled-channels optical framework to study electron scattering from atomic hydrogen at 54.42 eV. Nine-state coupled-channels calculations with nonlocal and local continuum optical potentials were performed. The results for differential, total and ionisation cross sections as well as the 2p angular correlation parameters lambda and R are comparable with other nonperturbative calculations. There are still discrepancies between theory and experiment, particularly for lambda and R at larger angles.
