abstract: Calculations on electron collisions with CO+ molecular ion are presented as a function of electron energy and CO+ geometry. Resonance positions and widths are obtained for the low- lying Feshbach resonances in the system. Plots of resonance curves suggest that low- energy dissociative recombination can occur via resonances of (1)Pi, (1)Delta, (3)Sigma(+) and 3 Pi symmetries. Electron impact electronic excitation is considered both for excitation to the first excited A (2)Pi state and to yield a dissociation cross section. The latter calculations suggest that the lower of two experimental measurements of this process is likely to be correct. Finally results are presented for bound states in the continuum for both (1)Sigma- and (3)Sigma(-) symmetries.
