We propose an original approach consisting in determining the mass attenuation coefficients in an energy range covering the L-, M- and N- absorption edges, including a detailed evaluation of the associated uncertainties, to derive precisely the binding energies. We investigated the Lα, Lβ and M spectra of Gd with an independantly calibrated high-resolution anti-parallel double-crystal x-ray spectrometer. All the lines were identified and found in excellent agreement with the binding energies previously derived. Morever, we identified for the first time M5−O2, M4−O2,3 and M4−N2,3 diagram lines.764915engDiagram line energiesMass attenuation coefficientsRadiationAtomic and Molecular Physics, and OpticsSpectroscopyjournal article10.1016/j.jqsrt.2019.106585https://www.scopus.com/pages/publications/85069858633
