Title: Note: Coherent resonances observed in the dissociative electron attachment to carbon monoxide

Succeeding our previous finding about coherent interference of the resonant states of CO{sup −} formed by the low-energy electron attachment [Tian et al. Phys. Rev. A 88, 012708 (2013)], here we provide further evidence of the coherent interference. The completely backward distributions of the O{sup −} fragment of the temporary CO{sup −} are observed with anion velocity map imaging technique in an electron energy range of 11.3–12.6 eV and explained as the results of the coherent interferences of three resonant states. Furthermore, the state configuration of the interference is changed with the increase of electron attachment energy.
