Scientific paper

Using the Solar Isotope Spectrometer on the Advanced Composition Explorer, we have measured the isotopic composition of neon at 24-72 MeV/nucleon in nine solar energetic particle events between 4 November 1997 and 16 November 1998. The 22Ne/20Ne ratio varies from ~0.7 to ~2 times the solar wind value from event to event, indicating significant mass fractionation in the acceleration and/or transport of these particles. The mass fractionation is strongly correlated with the Fe/O and Na/Mg element abundance ratios, suggesting that elemental and isotopic fractionation are both governed by the ionic charge to mass ratio.
