in collisions with low-energy electrons*

Preliminary results from the theoretical approach to model the dissociative recombination (DR) and ro-vibrational (de)excitation (R-(d)VE) of CF⁺ will be presented. The approach combines the MESA code (Molecular Electronic Structure Applications), the UK R-matrix method for fixed-nuclei electron-ion scattering, the vibronic frame transformation with outgoing-wave dissociative functions obtained using a complex absorbing potential and molecular quantum-defect theory. Comparison with previous calculation (from complex Kohn variational method and multichannel quantum defect theory) and experimental results (Test Storage Ring in Heidelberg) are shown. The study of CF⁺ is of relevance for astrochemistry and more specificly in diffuse interstellar media (ISM) as it regarded as a possible probe for molecular hydrogen column density.
