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.
