On Electron Attachment and Detachment Processes in Dry Air at Low and Moderate Constant Electric Field

Results of theoretical research on ionization of dry air at different low and moderate values of constant electric field are described. Ionization processes at subthreshold, near-threshold, and suprathreshold values of electric field have been considered. Special attention to the processes of electron attachment to oxygen molecules and electron detachment from negative ions has been paid. New data on the detachment of electrons from oxygen molecular negative ions are taken into account. Plasma ionization during thermal instability has been considered.
