Abstract
A local, central potential is used to describe elastic scattering of charged particles by atoms. This accounts for second-order direct and first-order exchange effects, the only parameter involved being the target dipole polarizability. Detailed values of differential, integrated elastic, and total cross sections are presented for electron-hydrogen scattering (50<or=E<or=200 eV) and electron-helium scattering (100 eV<or=E<or=1 keV). Values of integrated elastic and total cross sections for positron scattering by hydrogen and helium are also given.Keywords
