Abstract

Using improved techniques for the analysis of the University of Iowa Pioneer 10 Jupiter encounter data, it has been possible to obtain what are believed to be significantly more reliable values for energetic electron (E sub e < 21 MeV) intensities within 10 Jovian radii of the planet. The nature of the revisions is such that the absolute intensity values for electrons 0.06 < E sub e < 21 MeV are reduced by factors as great as 10 from previous estimates made for the University of Iowa data at L < 6. Previously published intensities at greater radial distances for E sub e < 21 MeV and at all radial distances for E sub E > 21 MeV are not affected by the revisions.
