Differential cross sections for the elastic scattering of electrons from atomic hydrogen. II. Medium energies

Abstract

Differential cross sections for the elastic scattering of electrons from atomic and molecular hydrogen have been measured at 30, 50, 100, and 200 eV. The results for atomic hydrogen are compared with various theoretical calculations based on both low-energy and improved high-energy approximations. The ratios of the total cross sections for elastic scattering of electrons from atomic and molecular hydrogen are also given for incident energies of 9.4, 12.0, 20, 30, 50, 100, and 200 eV.
