Abstract

The individual isotopes of galactic cosmic ray Ne, Mg, and Si at ~100 MeV/nucleon have been clearly resolved with an rms mass resolution of ~0.20 amu. Our results suggest that the cosmic ray source is enriched in ^(22)Ne, ^(25)Mg, and ^(26)Mg when compared to the solar system. In particular, we find (^(25)Mg + ~^(6)Mg)/^(24)Mg = 0.49+/-.2314 compared to the solar system value of 0.27, suggesting t~at the cosmic ray source and solar system material were synthesized under different conditions.
