PIXE analysis of ancient Greek copper coins minted in Epirus, Illyria, Macedonia and ThessalyPIXE analysis of ancient Greek copper coins minted in Epirus, Illyria, Macedonia and Thessaly Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-101996enAncient copper coins from Greek cities and confederacies such as Amphipolis, Veroia, Dion, Edessa, Magnetes, Stobi, Apollonia, Kerkyra, Pella, Philippoi, Phoenike, and the Macedonian and Thessalian Koina, were analyzed non-destructively by proton induced X-ray emission (PIXE) after removal of the patina. The copper coins were minted during Roman Imperial times (31b.c.–268a.d.). Eleven elements were determined quantitatively. The correlation between the composition and the minting time is examined. The results are compared with those of a previous study for coins from the cities of Nikopolis in Epirus and Thessaloniki in Macedonia, in the same period.Δημοσίευση σε επιστημονικό περιοδικόhttp://creativecommons.org/licenses/by/4.0/Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms109-110662–666 Kallithrakas-Kontos Nikolaos Καλλιθρακας-Κοντος Νικολαος Katsanos Anastasios Κατσανος Αναστασιος Potiriadis C.
