Abstract

The energy spectra of ions 3He, 4He, C, O and Fe with energies of 0.04–2 MeV/nucleon were studied at 1 AU in solar-wind streams from near-equatorial coronal holes during the decline of solar activity in cycle 23 according to the information of the ULEIS, SWICS, and SWEPAM instruments installed onboard the ACE spacecraft. The results of this work show that suprathermal ions from coronal holes are Maxwellian solar-wind ions accelerated on the Sun and/or in interplanetary space and form a high-energy contribution to solar-wind ions (a suprathermal “tail” in the energy distribution of solar-wind ions). The energy spectra of accelerated “tail” ions have different dependences on energy, which indicates different mechanisms of their acceleration. The relationship between the intensity of suprathermal ions and the speed of the solar wind indicates the effectiveness of the acceleration of Maxwellian solar-wind ions.
