The neon isotopic abundances have been measured by the ACE-CRIS experiment and were obtained in seven energy intervals over the energy range of ~ 80<= E<= 280 MeV/nucleon. The ^22Ne/^20Ne source ratio is derived using the measured ^21Ne abundance as a ``tracer" of secondary production of the neon isotopes. Our results show that the ^22Ne/^20Ne abundance ratio at the cosmic-ray source is a factor of 5.0±0.2 greater than for the solar wind. The GCR ^22Ne/^20Ne 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 Wolf-Rayet models in which GCRs at earth preferentially sample material from the galactic interior provide predictions for the ^22Ne/^20Ne ratio and other isotope ratios. The CRIS neon, magnesium, silicon, and iron isotopic source abundance ratios will be compared with model predictions.
