Theoretical X-ray relative intensities at incident photon energies across the Li(i=1-3) absorption edges for Yb

The intensity ratios, ILk/ILα1 (k=l, η, α2, β1, β2,15, β3, β4, β9,10, γ1,5, γ6,8, γ2,3, γ4) and ILj/ILα (j = β, γ) have been evaluated at incident photon energies across the Li(i=1-3) absorption edge energies of 70Yb using theoretical data sets of different physical parameters, namely, the Dirac-Hartree-Slater (DHS) and the Dirac-Fock (DF) model based Li(i=1-3) sub-shell photoionization cross sections, the DF model based X-ray emission rates, and the DHS model based fluorescence and Coster-Kronig yields in order to highlight the importance of electron exchange effects at photon energies in vicinity of the absorption edge energies.
