Angular distributions for the elastic scattering of electrons by hydrogen and helium atoms were calculated by the second order potential method of Bransden and Coleman (J. Phys. B. Atom. Molec. Phys.; 5: 537-45 (1972)), using a partial wave expansion and allowing for exchange, in the energy interval 50 to 200 eV. Good agreemert with experimental data is obtained except at large angle scattering, for which the calculated values are up to 25% smaller than those measured. (auth)
