✦ Synopsis
The XRF analysis of TbDyFe thin Ðlm results in a multiple overlap between the Ka and Kb characteristic X-rays of Fe and the L X-rays of Tb and Dy, hence it is not a trivial procedure to extract quantitative information about the atomic ratios of the various elements in the Ðlm. To overcome this problem, two annular radioactive sources, 109Cd and 241Am, were employed in the XRF analysis of the Ðlms. By combining their results together with the experimentally determined sensitivity constants and relative intensities of the various characteristic x-rays, the overlapping x-rays are resolved and the composition of the Ðlms can be determined.
