Abstract
Rapid dissociative recombination of in a flowing, helium afterglow has been shown to be an efficient source of CO in the a 3Π metastable state. Ions produced by mixing CO2 with He(23S) recombine to produce a CO metastable afterglow with a number density as great as 109 cm−3. Monitoring of the (a 3Π—X 1Σ) Cameron transition in CO was used to study the lifetime and quenching of CO(a 3Π) by CO2, N2, NO, and He. Recombination of also produces CO in the d 3Δ and a′ 3Σ states.
