Electron scattering in ozone and chlorine dioxide

Abstract

Total cross-sections are reported for the scattering of electrons from ozone and chlorine dioxide (OClO) for energies in the range of 9 meV to 10 eV. The measurements were made in transmission experiments using synchrotron radiation photoionization apparatus with an energy resolution in the incident electron beam of (FWHM). The absolute accuracy of the cross-sections is limited both by experimental difficulties with respect to strong rotationally inelastic forward scattering, due to the dipolar nature of the target molecules, and by the composition of the target gases, which may depart significantly from pure or OClO.
