Absolute elastic differential electron scattering cross sections for carbon monoxide and molecular nitrogen in the intermediate energy region

This paper reports absolute elastic differential scattering cross sections (DCS) for electron impact on CO and N 2 in the energy range 20-100 eV and angular range 20-120'. The results are obtained using a relative flow technique in which the DCS of CO is compared with that of helium at each angle and energy and the DCS of N 2 is compared directly with the DCS of CO. The results of elastic DCS of neon are presented as a check on the experimental procedure.
