Absolute total cross sections for electron-CO₂scattering at energies form 0.5 to 3000 eV

Abstract

Employing two different experimental techniques, absolute total cross sections for e--CO2 scattering have been measured over a very wide energy range between 0.5 and 3000 eV. The cross section function exhibits a sharp increase below 1.5 eV and a resonant maximum around 3.8 eV. It then rises again up to a broad maximum near 30 eV and then decreases slowly. A very broad feature was observed centred at an energy of about 300 eV and extending from about 200 to 600 eV. Comparison is made with other available measurements and calculations.
