The reduction method developed previously for many-particle scattering is applied here to derive new sets of coupled equations for electron scattering from atomic targets at low energies, fully taking into account the exchange effect and target distortions. The reduced matrix equations have simpler structure than the Faddeev-Watson equations, with the iteration kernels connected only in those channels which are explicitly taken into account. Scatterings by atomic hydrogen, helium, and lithium targets are considered, and the resulting formalism is compared with the earlier work of Faddeev and others. Various approximation procedures are described, and their applicability is tested on the electron-hydrogen scattering system.
