Scattering of Electrons by Neutral Atoms

Abstract

A recent reformulation of the theory of electron scattering by atoms---in which those scatterings, real or virtual, that leave the state of the atom unchanged are separated off from the remainder---has been generalized to include the effects of the Pauli principle. The case where the Hartree approximation suffices to describe the atom is considered in detail, including a calculation of the "scattering potential" to second order.
