Emissions X K du manganèse: comparaison entre les spectres du métal et d'une source de 55Fe

Abstract : The Mn K x-ray emission spectra in metal and 55Fe source have been analyzed and energies, shapes and intensities of the Kα and Kβ emissions as well as Kβ/Kα ratio have been determined. A good agreement is obtained between the experimental data and the simulated spectra from MCDF calculations for the free atom and ions. Then, the shape and the intensity ratio of the emissions and their variation as a function of the 3d electron number, i.e. of the Mn oxydation number, are well described from the calculations. It is deduced that, for the transition elements, the emissions between inner shells essentially depend on the interaction of the inner hole with the d sub-shell and are well described with the help of an atomic model.
