Scientific paper
A numerical model has been developed for atomic hydrogen densities in the Titan hydrogen torus which includes the effects of occasional collisions. The torus is found to be azimuthally symmetric with the density sharply peaked at Titan's orbit and decreasing rapidly in the radial outward and perpendicular directions and more gradually inward from 17 to 5 Rs. The energetic hydrogen atoms from Saturn's upper atmosphere were also investigated. Collisions of these Saturnian atoms with the torus population do not significantly affect the torus density and in fact will lead to a net loss of bound torus atoms if their launch speeds from Saturn extend above roughly 40 km/sec.
