Quantitative Results of XRF Analysis of Ancient Coins by Monochromatic X‐ray Excitation

Abstract

The analysis by XRF applied to old coins is improved by use of monochromatic X‐ray excitation of variable energy. In addition the effects of relief and irregular shape are eliminated. A method of absolute quantitative analysis without any reference standard has been set up. Results of the analysis of 52 early Greek and 4 late Roman empire gold coins are reported.
