We apply the convergent close-coupling (CCC) method to calculation of 40-eV electrons scattering on the ground state of helium. We present the differential cross sections up to the [ital n][le]3 levels, as well as the electron-impact coherence parameters for the 3 [sup 1][ital D] state. We find our results to be in excellent agreement with the measurements. It is shown that at this energy treating the target continuum has a large effect on the presented results, and for this reason the CCC theory is the only one that is able to obtain agreement with experiment. Integrated, total ionization, and total cross sections are also presented, and are found to be in excellent agreement with experiment.
