ANOMALOUS HYDROGEN AND HELIUM SPECTRA AT THE TERMINATION SHOCK FROM ENERGETIC NEUTRAL ATOMS FLUX INTENSITY MEASUREMENTS

摘要

The energetic neutral hydrogen and helium flux intensities measured by CELIAS/HSTOF on SOHO are combined with the high-energy cosmic ray data to estimate the energy spectrum of the anomalous hydrogen and helium cosmic ray ions at the termination shock, assuming that these ions are the source of the neutral atoms observed by HSTOF. The analysis is done separately for the years 1996-97 (the quiet Sun period, which contributed most of the HSTOF energetic neutral atoms data) and for the remaining period of observations.
