Increasing in the rate constant for dissociative attachment of electrons to hydrogen molecules by vibrational pumping during flow in a channel

An investigation is made of the electron-vibrational kinetics in a stream of vibrationally excited hydrogen flowing in a channel. It is shown that for suitably organized flow and a suitable choice of material for the channel walls, the rate constant 〈K DA〉 for dissociative attachment of electrons to hydrogen molecules may be increased substantially. The effect is controlled by the mean vibrational energy 〈E v (0) 〉 of the H2 molecules entering the channel.
