Abstract
An experimental arrangement is described which allows the detection of low gas densities by resonance fluorescence in the vacuum ultraviolet. As a light source a capillary discharge through helium was used. Fluorescence signals as a function of density have been measured in krypton, deuterium, and hydrogen, and the results have been compared with calculations. Detection limits of 3·109 atoms/cm3 have been obtained.
