Heavy-Element Abundances in HE3 - Rich Events
Abstract
Abundances of the elements He through Fe observed on the ISEE-3 during He(3) rich events are reported. Ratios of He(3)-He(4) of not less than about 1, and Fe/O of greater than 1 are found, and rather large event-to-event variations in C, O, Ne, Mg, Si, and S are seen superposed upon the general trend of heavy element enhancement. It is concluded that the discontinuous variation of the neighboring elements in the He(3) rich events could result from differences in the electron temperature of the material prior to injection that give rise to differences in the dominant charge states and cyclotron frequencies of different elements.
