The ratios are decreasing functions of energy from 5 GeV/n to approximately 80 GeV/n, as expected. However, an unexpected sharp upturn in the ratios are observed for energies above 100 GeV/n for all elements from Z=16 to Z=24. Similar upturn but with lower amplitude was also discovered in the ATIC-2 data for the ratio of fluxes of abundant even nuclei (C, O, Ne, Mg, Si) to the flux of iron. Therefore the spectrum of iron is significantly different from the spec","authors_text":"A. D. Panov, A. R. Fazely, E. N. Kouznetsov, E. S. Seo, G. L. Bashindzhagyan, H. S. Ahn, J. Chang, J. H.
