The isotopic composition of solar flare accelerated magnesium
Abstract
We report observations of energetic solar particles from the 1978 September 23 solar flare in which the three stable isotopes of magnesium are clearly resolved with a mass resolution of 0.23 amu. We find ^(25)Mg/^(24)Mg = 0.14 (+0.05, -0.02) and ^(26)Mg/^(24)Mg = 0.15 (+0.04, -0.03) in the energy interval 12-36 MeV per nucleon. These observations are consistent with terrestrial magnesium isotopic abundances.
