摘要：

The differential equations of the second-order potential model are converted into a set of integral equations for the scattering amplitudes. After making a partial-wave decomposition and retaining only the physical amplitudes in the kernel, the resulting equations are used to calculate the cross sections for elastic scattering of electrons and positrons by hydrogen, helium and lithium within the energy ranges of 20-500 eV, 40-500 eV and 10-200 eV, respectively. The results are compared with the calculations of other workers.
