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(-) 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(-) fragment of the temporary CO(-) 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.
