Title: A Galactic Cosmic Ray Electron Intensity Increase of a factor of up to 100 At Energies between 3 and 50 MeV in the Heliosheath between the Termination Shock and the Heliopause Due to Solar Modulation As Measured by Voyager 1,
Abstract: We have derived background corrected intensities of 3-50 MeV galactic
electrons observed by Voyager 1 as it passes through the heliosheath from 95 to
122 AU. The overall intensity change of the background corrected data from the
inner to the outer boundary of the heliosheath is a maximum of a factor ~100 at
15 MeV. At lower energies this fractional change becomes less and the corrected
electron spectra in the heliosheath becomes progressively steeper, reaching
values ~ -2.5 for the spectral index just outside of the termination shock. At
higher energies the spectra of electrons has an exponent changing from the
negative LIS spectral index of -1.3 to values approaching zero in the
heliosheath as a result of the solar modulation of the galactic electron
component. The large modulation effects observed below ~100 MV are possible
evidence for enhanced diffusion as part of the modulation process for electrons
in the heliosheath.
