Variational Calculation of the Scattering Cross Section for Nearly Zero Energy Electrons by Hydrogen Atoms

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The scattering of low-energy electrons by atomic systems is of some interest as one of the fundamental processes which occur in ionospheric and astrophysical phenomena. Mere detailed knowledge of the scattering pro cess would also be of great aid in understanding certain aspects of gas discharges.
