Abstract: | We discuss isotopic abundance measurements of heavy (6 ≤ Z ≤ 14) solar energetic particles with energies from ∼15 to 70 MeV/nucleon,
focusing on new measurements made on SAMPEX during two large solar particle events in late 1992. These measurements are corrected
for charge/mass dependent acceleration effects to obtain estimates of coronal isotopic abundances and are compared with terrestrial
and solar wind isotope abundances. An example of new results from the Advanced Composition Explorer is included.
This revised version was published online in June 2006 with corrections to the Cover Date. |
