Abstract
We report on a new method to determine the collision rates for ionization by means of pair collisions (Paarstöße) and stepwise ionization, respectively. This method is based on the experimental and theoretical study of the dynamical behaviour (impedance behaviour) of the positive column of a low‐current discharge at low pressure.
