Abstract

This exploratory paper demonstrates the quantitative response of H₂, N₂, and O₂ in 50% argon–50% helium to a 20-A dc arc and 1% thoriated-tungsten electrodes. This work also illustrates the feasibility of exciting the spectra of these gases, as well as chlorine, at atmospheric pressure and at other relatively simple conditions with a minimum of special facilities.
