Pixe Analysis of Some Ghanaian Coins Using a 1.7 mv Pelletron Accelerator

Joseph B Tandoh

The elemental composition of some Ghanaian coins spanning from the years 1967 to 2007 have been successfully analysed using a newly installed 1.7 MV Pelletron accelerator at the Ghana Atomic Energy Commission. Using Particle Induced Xray Emission (PIXE) spectrometry, this study attempts to relate the major composition of these coins to the economic state of the country at the year of minting and also to validate the PIXE method used at the Centre. This work demonstrates that the Accelerator Research Centre has the capacity to analyse mintage coins in Ghana.
