| Abstract: | At densities above 50 Amagats, light of frequency 2.818 x 104cm-1 ionizes efficiently argon gas containing less than 1 part per million of impurities. For a given density we find for the number of free charges produced a square law dependence on light intensity. At constant light intensity the number of free charges produced varies approximately like the sixth power of density in the range 200–500 Amagats. |
