Excitation of carbon monoxide by electron impact in the 8–17 eV energy range

The excitation of carbon monoxide by electron impact has been studied in the energy range from 8 to 17 eV using an optical method. The excitation of several states has been detected in the emission spectral range between 180 and 550 nm. Excitation functions for the A1Π and a′3Σ+ states have been measured in the near-threshold energy region and are compared with recent experimental and theoretical results.
