Elastic Scattering of Low-Energy Electrons by Atomic Hydrogen

Authors:

Abstract
The differential and total cross sections for elastic scattering of electrons by atomic hydrogen are calculated below the threshold for excitation of the second target quantum level (10.2 ev). A close-coupling approximation is used in which the total wave function is expanded in hydrogen eigenstates, and only terms corresponding to the 1s, 2s, and 2p states are retained; the wave function is symmetrized or antisymmetrized explicitly.
