摘要：

The purpose of this work is to undertake a detailed scientific investigation both on the alloy chemical composition and on the thickness of the gold foils of one of the most interesting wreaths from the National Archaeological Museum of Taranto (MArTA), Italy. This precious golden crown, which presumably dates back to the Hellenistic period, consists of eighteen gold leaves, whose chemical composition and thickness were determined in situ, and non-destructively, by using an energy dispersive X-ray fluorescence (EDXRF) portable instrument. Then, attenuation measurements of 59.6 keV gamma-rays from a source of Am-241, were carried out to determine the thickness of the leaves. The results demonstrate that the analysed leaves have different chemical composition and various thickness.
