Dissociative Recombination of CF$^+$
Abstract
This work presents our theoretical study of the dissociative recombination (DR) of the closed-shell diatomic system CF based on an approach recently applied to the CH molecule. Our extended treatment uses the UK R-matrix theory and the multichannel quantum-defect theory procedure to uniformly resolve the direct and indirect mechanisms of DR while bypassing explicit dissociative state and electronic coupling calculations. The theoretical results exhibit good overall agreement with previous experimental measurements. At lower scattering energies, good agreement is found only if the rotational structure of the ion is included and the theoretical cross sections are averaged over initial rotational levels corresponding to the temperature at which the experimental measurements were made. At higher scattering energies, our rotationally resolved results are very similar to those obtained without including the ion's rotational structure.
