Losses of Radiation Belt Energetic Particles by Encounters With Four of the Inner Moons of Jupiter

Based on an improved model of the moon absorption Jovian radiation belt particles, we investigate quantitatively and comprehensively probabilities particle lifetimes due to encounters with four inner moons Jupiter (Amalthea, Thebe, Io, Europa) inside L < 10. Our results demonstrate that resultant average energetic protons electrons vary dramatically between ?0.1 days well above 1,000 days, showing a strong dependence equatorial pitch angle, kinetic energy orbit. The against are shortest for Io (i.e., ?0.1–10 days) longest Thebe up thousands days), in Europa Amalthea. Due diploe tilt angle effect, markedly below = 67°. Overall, electron exhibit weak dependence, but proton strongly dependent angle. decrease monotonically substantially energy, roughly constant at energies <?10 MeV, increase around Kepler velocities (?10–50 MeV), quickly even higher energies. Compared averaged lifetimes, longer few MeV shorter tens MeV.
