Measurements of the neon isotopic abundances by the ACE-CRIS experiment have been obtained in seven energy intervals over the energy range of ˜ 80 ≤ E ≤ 280 MeV/nucleon. The 22 Ne/20 Ne source ratio is derived using the measured 21 Ne abundance as a tracer of secondary production of the neon isotopes. We find that the 22 Ne/20 Ne abundance ratio at the cosmic-ray source is a factor of 5.0 ± 0.2 greater than for the solar wind. The GCR 22 Ne/20 Ne ratio is also shown to be considerably larger than that found in anomalous cosmic rays, solar energetic particles, and most meteoritic samples of matter. Recent two-component WolfRayet and supernovae models in which GCRs at Earth preferentially sample material from the galactic interior provide predictions for the 22 Ne/20 Ne ratio and other isotope ratios. We will compare the CRIS neon, magnesium, silicon, and iron isotopic source abundance ratios with predictions from these models.
