deals with the application of the optogalvanic effect (the impedance change in a feebly electrically excited gas or metal vapour due to the absorption of an irradiating light) in atomic spectroscopy. this impedance change is easily recorded and provides a simple non-optical detector to measure the modification of the atomic level populations under the radiative absorption process associated with the advent of the tunable dye laser, the optogalvanic detection provides a valuable spectroscopic tool to investigate the atomic structure properties from the excited levels, mainly for high lying rydberg level studies. use of the hollow cathode lamp as a sputtering device to generate atomic vapours, opens the future to this method for studying refractory elements
