A second-order equivalent (optical) potential for elastic scattering has been constructed by expanding the intermediate states in a set of pseudostates, avoiding the closure approximation used in the method of Bransden and Coleman (1972). Using this potential the differential cross section for the elastic scattering of electrons by atomic hydrogen has been calculated for a number of energies in the range 1 to 100 eV. Good agreement is obtained with experimental data of Williams (1975) except at small angles in the interval 8-30 eV for which the calculated cross section is larger than the data. A comparison is made with the results of other models and possible improvements are discussed.
