Measurements of L x-ray intensity ratios for $_{51}$Sb at incident photon energies across its L$_{i}$(i=1-3) edge energies

The Ll/Lα, Lβ/Lα and Lγ/Lα intensity ratios have been measured for 51Sb at different incident photon energies across its Li(i=1-3) sub-shell absorption edge energies using synchrotron radiation as photon source. These experimental values have been compared with the two different sets of intensity ratios calculated using the photoionization cross sections based on the relativistic Hartree-Fock-Slater model, the X-ray emission rates based on the Dirac-Fock model and two sets of the fluorescence and Coster Kronig yields based on the DHS model and the semi-empirical values tabulated by Krause.
