The authors discuss two discrete-basis-function approaches to the solution of the T-matrix equations for the scattering of electrons by atoms or molecules. Both methods, one of which is based on the Schwinger variational principle, have major advantages over the previously proposed T-matrix methods and do not require large-basis-set expansions. Results are reported for s- and p-wave scattering for helium.
