Heavy ion composition in solar flares at low energies, 1973-1977The composition of solar flare particles near 1 MeV/nucleon has been surveyed for the major species between H and Fe over a four-year period using the IMP-8 ULET instrument. The average composition for the larger flares is found to be remarkably similar to that found by previous studies at energies greater than 10 MeV/nucleon. Variations in abundance are found to be well ordered by atomic number. It is suggested that such a smooth variation in abundances is due to an acceleration mechanism which preserves the main features of the ambient composition of the accelerated material, at least in the larger flares.
