A close-coupling calculation using a nine-state pseudostate expansion is performed in the intermediate-energy range for a simplified model of electron-hydrogen scattering. The resulting elastic scattering and excitation cross sections exhibit rather narrow structure below pseudothresholds. Except for this narrow structure, the cross sections have converged to the exact results and the T-matrix elements have converged to the previously corrected T-matrix elements for a smaller basis set.
