The energy spectrum of water-group pick-up ions with energies >35 keV observed during the encounter of comet Giacobini-Zinner by the ICE spacecraft is examined using data from the EPAS experiment, combined with published data from the ULECA sensor. In the plasma frame the combined spectra consist mainly of a steeply-falling tail extending to energies of a few hundred keV, but there is also evidence for flattening at speeds somewhat below the local pick-up speed. The latter feature is most evident in the solar wind outside the mass-loaded region of slowed flow, where the local pick-up speed is sufficiently fast that it falls within the range of the combined EPAS and ULECA data. Above the local pick-up speed the ion distribution function is well approximated by a decreasing exponential of ion speed. The characteristic speed of this distribution increases as the comet is approached. It is demonstrated that EPAS data can give detailed information on this portion of the spectrum with 32 s time resolution.
