Description:
The Phoenix I instrument on the S81-1 mission was designed to resolve isotopes in the charge range He to Ni. Analysis of four periods of moderate flare activity shows no strong evidence for mass dependent acceleration in the range C to Si; indeed, the mass abundance ratios are consistent with 'solar system' composition. However, the average Ne-22/Ne-20 ratio for these periods is 0.060 (+0.045, -0.023), i.e. about one standard deviation below ratios reported earlier for solar energetic neon.
