List of Figures
F-1. Relationships between PLASMAKIN and other program units or data files.
F-2. Representation of the ordering of species in PLASMAKIN. The electrons have the highest index of the charged species. Region (a) represents the neutral, excited species and region (b) the charged non-excited atomic and molecular species.
F-3. Representation of the ordering of reactions in PLASMAKIN. Regions (a) and (b) represent, respectively, the number of direct and reverse gas collision processes between atoms and molecules.
