Reactive collisions between electrons and NO⁺ions: rate coefficient computations and relevance for the air plasma kinetics

Abstract

−5 eV and 10 eV have been performed, with a method based on the Multichannel Quantum Defect Theory. Comparisons of the DR rate coefficients with the plasma experimental results give a good agreement, confirming that the vibrationally excited NO + ions recombine more slowly than those in the ground state. Also, our ground state IC rate coefficients are very similar with previously computed R-matrix data. The rate coefficients have been fitted to a modified Arrhenius law, and the corresponding parameters are given, in order to facilitate the use of the reaction data in kinetical plasma modelling.

A theoretical study of the dissociative recombination of SH+ with electrons through the 2Π states of SH

“…This interaction is effective at short electron-ion and internuclear distances typical of the reaction zone. (ii) Computation of the reaction matrix K, by adopting the second-order perturbative solution of the Lippmann-Schwinger integral equation, 50,57,58 written in the operator form as…”

Computed bound and continuum electronic states of the nitrogen molecule

“…This work will follow a similar study for NO in which R-matrix data [20] was used as input for MQDT calculations. This study gave excellent agreement with experiment [34] and was then extended to treat processes involving vibrationally excited target states [35]. The calculations on NO however, relied on adjusting the position of the ab initio curves after comparison with spectroscopic data for the NO Rydberg states.…”

Theoretical study of the mechanism ofH2O+dissociative recombination

“…Some of the peaks can be explained by tunneling resonances (shape resonances) formed by barriers in the potential energy curves. As seen for other systems, the regular oscillations above 4 eV are due to energy dependence of the electron capture probability [37,38]. For collision energies below 3 eV electronic resonant states of 3 A ′′ symmetry dominate, while above this energy, 3 A ′ states become important.…”
