Inelastic scattering and stopping power for electrons in O2 and O3 at intermediate and high energies, 0.3–5 keV

In this study, the stopping power for electrons in O2 and O3 molecules is reported for incident energies ranging from 300 to 5000 eV. The present results have been obtained by combining the calculated inelastic electron scattering cross-sections with an experimental energy loss procedure. Calculations have been carried out by means of a quasifree absorption model whose reliability has been checked by comparison with the electron scattering total cross section measured in a transmission beam experiment. Results for O2 are compared with high energy stopping power data available in the literature. For O3, these are the first results of the stopping power for electrons.
