The relative intensities of L-subshell X-ray fluorescence (XRF) for elements with atomic numbers 62≤Z≤83 were measured at two excitation energies: 18 and 23 keV using a synchrotron radiation source at a beamline of the Synchrotron Light Center for Experimental Science and Applications in the Middle East (SESAME), Jordan. The experimental measured results of the relative intensities were compared with the calculated results using the sub-shell fluorescence yield and the Coster-Kronig transition probabilities recommended by Campbell and the values based on the Dirac-Hartree-Slater (DHS) model by Puri. The experimental and theoretical results are in agreement.In this work, L XRF relative intensities for the elements Sm, Gd, Tb, Er, Ta, W, Re, Hg, Pb, Bi at energies 18 and 23 keV were measured. |
