Theoretical Angular Distributions for Elastic e-H Scattering

Abstract

The differential cross section for electrons elastically scattered by hydrogen atoms are calculated for incident electrón energies of 100 eV and higher. The polarization and distorsión ofth e electronic wave function are included at second order by replacing an infinite number of virtual intermedíate states by a single State with parametric energy. This parameter is evaluated by uslng the Schwinger variatlonal principie. Agreement with experimental valúes is good.
