Abstract
Direct pulsed‐laser photoionization of neutral atomic hydrogen or deuterium in a discharge plasma is shown to result in large voltage changes across the electrodes. The ground‐ and excited‐state densities and the translational temperature of the H and D atoms within the plasma are probed by this technique.Keywords
