New system for measuring partial densities of metal vapours by atomic resonance absorption spectroscopy I. Introduction and system principle
A new system is described for measuring partial densities of monatomic metal vapours in a high vacuum environment. The arrangement consists of a cylindrical vaporizing probe heated electrically and a measuring light beam crossing the vapours in a direction parallel to the probe’s axis. The frequency of the light corresponds to a properly chosen resonance line of the vapour atoms to be measured; as the light absorption is proportional to the number of these vapour atoms in the optical path, its partial density can be determined.
