Heavy ion abundances and spectra and the large gradual solar energetic particle event of 2000 July 14

We compare the spectra and abundances of heavy elements of atomic number Z in the range with 34 less than or equal to Z less than or equal to 40 those of He, C, O, Ne, Si, and Fe, as observed on the Wind spacecraft, in the la rge solar energetic particle (SEP) events of 1998 April 20 and 2000 July 14 . This is the first time that spectra of the rare, trans-Fe, 34 less than o r equal to Z less than or equal to 40 ions have been measured in SEP events . We use the systematic dependence of the spectral e-folding energies on th e charge-to-mass ratio (Q/A) of the species to estimate ionization states o f each species. Ionization states of Q similar to 11 for ions with 34 less than or equal to Z less than or equal to 40 are comparable to those for Si and Fe.
