The cloud of relativistic electrons which forms the Jupiter radiation belts at a distance of a few Jovian radii from the planet is considered. The inner belt is shown to consist of electrons with about three times the energy of those in the outer zone, and to have an equatorial density which is about one half the peak density in the outer zone. The pitch angle distribution of the electrons in the outer zone becomes gradually more confined to the magnetic equator with increasing distance from the planet.
