L X-ray fluorescence cross-sections measurements for elements Ba, La and Ce at synchrotron radiation energies 7, 8, 9 and 10 keV

Ll, Lα, Lβ and Lγ1 X-ray fluorescence cross-sections have been measured for the elements Ba, La and Ce at 7, 8, 9 and 10 keV synchrotron radiations. A Peltier cooled Vortex solid state detector (SII Nano Technology, USA) with an energy resolution of 138 eV at 5.96 keV X-rays was employed for the analysis. The experimental results were compared with the theoretical values estimated from the data of Puri et al. (1993) and Campbell (2003). Two different models Dirac-Hartree-Slater (DHS) and Dirac-Fock (DF) were used to compare the theoretical and experimental results. Most of the experimental measurements were found in good agreement with the theoretical values of Puri et al. (1993) based on DF model. •L XRF cross-sections measured for three elements Ba, La and Ce at 7–10 keV.•Synchrotron radiations with Peltier cooled Si(Li) detector was employed.•DHS and DF models with physical parameters of Puri and Campbell were used.•Results are in good agreement with theoretical values of Puri and DF model.
