Abstract
Various total cross sections and elastic differential as well as momentum-transfer cross sections for electron scattering by oxygen atoms are calculated for incident energies ${\mathit{E}}_{\mathit{i}}$=8.7--1000 eV. A partial-wave analysis of the local, complex, energy-dependent optical potential yields reliable total cross sections. Discrepancies between theories and experiment exist at low energies, but a reasonable energy-variation picture of various ${\mathit{e}}^{\mathrm{\ensuremath{-}}\mathrm{\ensuremath{-}}}$O cross sections emerges. The present total inelastic cross sections are similar to but higher than the recommended total ionization cross sections.
