Differential and integral cross sections for elastic electron scattering from CF2

Abstract

We report the results of measurements and calculations of differential and integral cross sections for elastic electron scattering from the CF2 molecular radical. The energy range of the present investigation was 2–20 eV, while the angular distributions were measured at specific angles within the scattered electron range 20°–135°. The calculations employed the Schwinger multichannel method and were carried out both in the static-exchange and static-exchange plus polarization (SEP) approximations, with generally quite good agreement found between the data and the SEP level results. This was particularly true at lower energies, illustrating the importance of correctly accounting for the polarization in these collisions.
