It was found to contain residual positive ions in excess of electrons. These residual ions amounted to 10 to the -4 times the total number of flowing atoms; a slight increase occurred with decreasing enthalpy input. This quantity also represented the only residual ions of the gas jet leaving the expansion nozzle at ambient temperature and a pressure of 0.25 mm Hg. Normalization of these ions was achieved by means of diffusion to the surface of the pipe recapturing the free jet.44 ppengCopyright is held by the author, unless otherwise indicated.
