Abstract

Average energy and concentration of electrons along the axis of a nitrogen afterglow tube have been measured by means of a movable Langmuir probe. Electrons with energies of more than 20 volts have been found throughout the afterglow. The experimental curves of potential and electron density distribution could be explained by solving the diffusion equation. It is shown that a part of the ions in the afterglow is produced by the collision of fast electrons with $N_{2}$ molecules.
