Scientific paper

Charged particle experiments on the Voyager spacecraft at Saturn can be used to provide some useful estimates on the charge exchange loss rate of magnetospheric particles in the atomic hydrogen cloud of Titan. The thermal plasma instrument measured the number density and ion and electron temperatures of the corotating plasma and thus the charge exchange loss time scale of the neutral gas; the low-energy particle detectors measured the flux of the energetic neutrals generated by charge exchange recombination of the hot magnetospheric plasma. These observational results together with known reaction rate coefficients can be used to compute the total H + H2 density in the hydrogen torus. As the Voyager UV spectrometer experiment determined the average number density of hydrogen atoms independently, a limit on the H2 density in the neutral torus region can be estimated. This method leads to an H2 density value of less than or approximately equal to 10/cu cm, considerably less than the limiting value for the ballistic motion of the neutral particles to be collisionally dominated.
