High Resolution Measurements of Solar Flare Isotopes


The individual isotopes of C, N and O are measured in the large solar particle event of August 1978. Limits are placed on mass dependent selection effects occurring in the solar flare by fitting a simple mass fractionation law to measurements of the C, N, O and Mg isotopes, to relate the SEP composition more directly to the composition of the sun. The individual isotopes are found to be consistent with solar system abundances, and the absence of any observable fractionation for C, O and Mg leads to the conclusion that solar neon is most likely neon-A with Ne-22/Ne-20 equals 0.12.
