In a recent article [Phys. Rev. A 88, 012708 (2013)], Tian et al. claimed coherent interference among the various negative ion resonant states involved in the dissociative electron attachment (DEA) to carbon monoxide (CO) by investigating ${\mathrm{O}}^{\ensuremath{-}}$ angular distribution using the anion velocity time-sliced map imaging technique. However, our recent detailed study [Phys. Chem. Chem. Phys. 17, 7130 (2015)] on DEA to CO using the identical technique shows that the above claim can be questioned.
