Abstract
From four years of data provided by the Ion Composition Instrument on ISEE-3, we have derived flux ratios of minor elements in the solar wind and found He/O = 75 ± 20 and Ne/O = 0.17 ± 0.02. These results are compared with recent solar energetic particle composition data and photospheric values, and they are discussed in the light of theoretical models of ionization and acceleration of heavy ions in the solar chromosphere and corona.
