Coulomb-Born Electron Impact Excitation Cross-Sections for Atmospheric Ions
Abstract
Coulomb-Born electron impact excitation cross-sections for thirty ground state transitions of the first three ions of nitrogen and oxygen have been computed for electron energies ranging from the threshold to 300 eV. Effective Gaunt factors for use in estimating cross-sections semi-empirically were also calculated and the reliability of such estimations is discussed. Comparisons with more elaborate theoretical cross-section calculations indicate that the Coulomb-Born results appear to over-estimate the cross-section near the threshold for intra-shell transitions, but not for the inter-shell transitions.
