In this work, we investigate the role played by associative ionization reactions in the memory effect of atmospheric pressure Townsend dielectric barrier discharges working in N 2 with a small addition of O 2 . Systematic laser-induced fluorescence measurements are carried out in order to provide the absolute densities of N and O atoms and NO molecules for different oxygen concentrations. The use of these data in a dedicated model allows us, in particular, to estimate the rate of the reaction ##IMG## [http://ej.iop.org/images/0022-3727/53/20/205201/dab7518ieqn1.gif] {$\text{N(}^\text{2}\text{P)+O(}^\text{3}\text{P)}\rightarrow\text{NO}^\text{+}\text{+}\textit{e}$} suspected of playing a significant role. According to the obtained results, this reaction is found responsible for a significant enhancement in the production of seed electrons between two successive discharges at 25 ppm of O 2 , in good agreement with experimental obse...
