Abstract
A constant or alternating electric field applied to graphite electrodes affects the absorption of light by alkali metal atoms in a flame and also the emission intensity. The weakening of the atomic absorption of potassium, rubidium, and cesium near the cathode has been studied both over the width (between the electrodes) and over the height (along the electrode and higher). The effect is connected with the fall in the partial pressure of the metal atoms resulting from a shift of the ionization equilibrium to the right.
