The current model generally accepted as the source of these hot atoms is the dissociative recombination of OZ, that is, O-2(+) + e(-) {\textendash}> O* + O* where the product O* atoms are translationally energetic. The determination of the extent of this population of superthermal atoms is an important endeavor. The present paper considers a simple model based on the Boltzmann equation for the energy and altitude dependence of the oxygen atom distribution function. The density and temperature distributions are determined with this distribution.}, keywords = {ESCAPE, FRACTIONATION, GEOCORONA, HYDROGEN, KINETICS, MARS, MODEL, NITROGEN-ATOMS, O(P-3) ATOMS, UPPER-ATMOSPHERE}, isbn = {0094-243X0-7354-0025-3}, url = {://000172834300017}, author = {Shizgal, B.
