N2 - We apply the Schwinger method, two Kohn-type methods, and three Harris-Michels-type methods to electron scattering by the same potential with the same sets of basis functions We also test a polynomial basis in the Schwinger method. We use Nesbet and Oberoi's method to avoid spurious singularities of the Kohn method Kohn and Harris-Michels methods show much better convergence to the accurate result than the Schwinger method.
