DOIAbstract
We present measurements of neon isotopic abundances from the ACE-CRIS experiment. These abundances have been obtained in seven energy intervals over the energy range of ∼80≤E≤280 MeV/nucleon. 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. These measured abundances agree well with previous experiments. The significance of these results is discussed
