Effects of absorption by Io on composition of energetic heavy ions.
The Galileo heavy ion counter is sensitive to ions with atomic numbers Z >/= 6 and energies greater than approximately 6 MeV per nucleon. During Galileo's passage through Jupiter's inner magnetosphere, the observed composition of these heavy ions was consistent with the presence of singly ionized iogenic O, Na, and S and highly ionized solar C, O, and Ne. The solar component is absorbed more strongly by Io because its gyroradius is smaller than Io's diameter.
