Abstract
The energy spectra of 4He, O, and Fe ions with energies of 0.04–2 MeV/nucleon, obtained by the ULEIS device on board the ACE satellite in the quiet time of 2006–2012, are analyzed. The obtained spectra of suprathermal ions from coronal holes were approximated by either a power function or a combination of a power and an exponential function. The approximation of 98 spectra yielded 2 < γ < 6, which could indicate different conditions in regions of particle acceleration in solar wind streams from coronal holes.
