Differential Cross Section of Electron Scattering from Molecular Hydrogen. II. b³Σ_<i>u</i>⁺Excitation

Abstract

Differential cross section(DCS) for the electron-impact H 2 (b 3 Σ u + ) excitation has been measured in the incident energy range from 12 to 60 eV and in the angular range from 10° to 130°. The electron transmission efficiency of the energy analyzer was calibrated using the secondary electron emission cross sections from N 2 molecule. The inelastic DCS is normalized to the absolute H 2 elastic DCS. Integral cross section is derived from the measured DCS. Measured DCS is compared with other experimental and theoretical results.
