Substantially larger calculations than previously possible are performed to examine how the convergent close-coupling method converges in the case of electron-impact ionization of atomic hydrogen. By studying the case of 27.2 eV incident electron energy, convergence and comparison with experiment is able to be considered together for both symmetric and asymmetric energy sharing. We find that, with Laguerre basis parameter choices of Nl = N0 − l and λl = λ, excellent agreement with experiment is obtained for all kinematical conditions and geometries considered.
