Charge transfer rate coefficients in collision of C2+ ions with CO and N2 molecular targets

► Calculation of rate coefficients for charge transfer processes between C2+ ions and the two isoelectronic molecules CO and N2 using ab initio calculation of potential energy curves and couplings. ► Comparison with recent measurements with cylindrical radiofrequency ion trap. ► Interest of this approach for the study of series of collision processes, in particular with molecular targets, diatomic or polyatomic molecules.
