Trans-Nickel Elements in Solar Energetic Particles
Abstract
The trans-nickel elements (Z ≥ 29) are some of the rarest in the Solar System; they typically are about 1/1OOOth to l/lOOOOth as abundant as iron (Z = 26). We present measurements of zinc and other transnickel elements in solar energetic particle (SEP) events observed by the Solar Isotope Spectrometer (SIS) in the energy range of 10-75 MeV/nuc. SIS is part of the Advanced Composition Explorer (ACE) spacecraft, presently in orbit about the Earth-Sun Ll point. The measured abundances of the trans-nickel elements are compared to tabulated meteoritic and photospheric abundances and to previous SEP measurements. The results may help to assess changes in composition due to SEP acceleration and transport.
