Dissociative recombination of N2OD+

Abstract

Branching ratios and absolute cross sections have been measured for the dissociative recombination of N₂OD⁺ using the CRYRING ion storage ring. The most dominating pathways were found to be those leading to N₂ + OD (46%) and the three-body break-up producing N₂ + O + D (40%). The production of N₂O is not observed. The cross section of the reaction could be fitted to the expression σ = 1.25 ± 0.25 × 10⁻¹⁵(E/eV)^{−1.24±0.02}, which leads to a thermal reaction rate of k(T) = 1.4 ± 0.1 × 10⁻⁶(T/300)^{−0.74±0.02} cm³ s⁻¹. The findings are compared with those of the related dissociative recombination of DOCO⁺ as well as with earlier flowing afterglow measurements.
