Low energy electron scattering from CO: absolute cross section measurements and<b><i>R</i></b>-matrix calculations

Abstract

Absolute cross sections for elastic scattering and rovibrational excitation have been measured with a crossed beam spectrometer and calculated, utilizing the R-matrix formalism, for incident electron energies between 1.0 and 30 eV. Particular emphasis is placed on the comparison between experiment and theory in the region below 5 eV where the cross sections are enhanced by a strong shape resonance.
