Abstract The properties of energetic water-group ions in the extended pick-up region surrounding comet Giacobini-Zinner are examined using 3-dimensional 65–95-keV ion observations from the EPAS instrument on the ICE spacecraft. The ion distribution is inferred to retain a significant ring-beam anisotropy beyond ∼4×105-km from the comet though effects of partial scattering are also present. Closer to the comet, the ions are found to be isotropic, or nearly so, in the solar wind frame due to increased scattering by MHD waves.
