    Investigation of Comet Wild-2 in terms of effective atomic numbers
    (Elsevier Ltd, 2015) Han I.; Ün A.; Alimb B.
    Effective atomic numbers (Zeff) and effective electron densities (Nel) of 69 samples collected from Comet Wild-2 within scope of Stardust mission were determined in the energy range from 1 keV to 100 GeV. The data were individually evaluated for Wild-2 olivines, pyroxene, FeANi sulfide and silicate glass samples to obtain remarkable information about Comet Wild-2. The photon energy and sample composition dependencies of obtained data were investigated. The results show that Zeff and Nel values depend strongly on chemical composition and interaction photon energy. The result of present study may be providing new and helpful knowledge about the Comet Wild-2 and ourSolar System. © 2015 COSPAR. Published by Elsevier Ltd. All rights reserved.
