Investigation of Atmospheric Ionic Spectra.
Abstract
As a preliminary to study of natural ionization in the atmosphere, ions from corona point discharge in air 20C, 740 torr have been studied by a high-resolution time-of-flight mobility apparatus with a best resolution (width of peak at half height) of 2.5 percent. It is believed this level of resolution has not been achieved before at these pressures. Relative intensities of some ions are influenced by magnitude of current in the discharge without change of mobility. Other ion mobilities are influenced by both humidity and current. In general greater humidity results in a slower centroid of mobility. The mobility spectrum of dry nitrogen is quite different from that of air at ordinary humidities. (Author)
