Precise lead isotope ratios measurements on Ebusus coins and on some Campanian imitations

摘要

In this work, precise measurements of lead isotope ratio in old coins from Ebusus are presented and the results are compared to data obtained from the analysis of imitation coins from Campania. Thermal ionization source (TIMS) was used for the measurements. Original coins minted by Ebusus are examined in order to have (certain) data to serve as a reference and then to be compared with coins of different origins or uncertain attributions. The lead isotope ratio resulted to be a valid parameter for the recognition and attribution of tested samples.
