Abstract
Motivated by the huge need for data for non-equilibrium plasma modeling, a theoretical investigation of dissociative electron attachment to the NO molecule is performed. The calculations presented here are based on the local-complex-potential approach, taking into account five NO− resonances. Three specific channels of the process are studied, including the production of excited nitrogen atoms N(2D) and of its anions N−. Interpretation of the existing experimental data and their comparison with our theoretical result are given. A full set of ro-vibrationally-resolved cross sections and the corresponding rate coefficients are reported. In particular, a relatively large cross sections for N− ion formation at low energy of the incident electron and for vibrationally excited NO target are predicted. Finally, molecular rotation effects are discussed.

Motivated by the huge need for data for non-equilibrium plasma modeling, a theoretical investigation of dissociative electron attachment to the nitric oxide (NO) molecule is performed
In order to supply further data for the non-equilibrium plasma modeling, and based on the same molecular data, in this letter we extend the calculations to its dissociative electron attachment (DA)
Among the nitrogen oxide compounds NxOy, the NO molecule and its ions have the greater impact on the environment and on the pollution caused by human activities [8, 9], being very important in many industrial technologies [10,11,12,13] and in the optimization of combustion processes of the fossil fuels [14, 15]
Summary
Motivated by the huge need for data for non-equilibrium plasma modeling, a theoretical investigation of dissociative electron attachment to the NO molecule is performed. Concerning the DA process, the theoretical studies are limited to very low scattering energy and to the few lowest vibrational states corresponding to the ground electronic state of NO, and only few low-lying resonant states of NO− [18] are taken into account.
