Abstract
The mass of gas ions formed in a glow discharge and aged up to impacts was determined by a Dempster type of mass-spectrograph. In hydrogen it is found that the primary ion, , changes within a few thousand collisions to , together with small quantities of . The nitrogen primary ions, and , attach to neutral molecules in about impacts to form and . In pure oxygen the ions consist almost entirely of with small quantities of . Air ions include all possible nitrogen and oxygen ions, the aged air ions consisting principally of , and together with the oxides of nitrogen. Charges are transferred from to NO, N and O. Water vapor is particularly active in acquiring a charge by transfer and ions may be most numerous in apparatus not baked out. No heavier clusters than were observed. No negative ions were observed. Some conclusions published in earlier work must be revised.
