Abstract

The results of large scale ab initio calculations of the rates for production of O(1D) by dissociative recombination of O2+ are presented for electron temperatures in the range 100–3000 K. A 1Δμ state is the dominant dissociative route from ν = 0 and a 3Σμ state is the most important route from ν = 1 and ν = 2. The calculated total rate for O(1D) production from ν = 0 is 2.21 (+0.21, −0.24) × 10−7 × (Te/300)−0.46 near room temperature. The ν = 1 and ν = 2 rates are about 17% and 47% maller, respectively, than the ν = 0 rate at 300 K.
