Abstract
Fluctuations of the emitted light intensity from a gaseous discharge through low pressure mercury vapour occur over a range of discharge current winch depends upon the saturation vapour pressure of the mercury. These fluctuations in the light intensity have been examined with photocells and are shown to be the result of the interaction of two kinds of moving striations, almost regular striations moving towards the cathode (positive striations), and irregular striations moving towards the anode (negative striations).
