The intensity ratios, I{sub Lk}/I{sub L{alpha}1} (k = l, {eta}, {alpha}{sub 2}, {beta}{sub 1}, {beta}{sub 2,15}, {beta}{sub 3}, {beta}{sub 4}, {beta}{sub 5,7}, {beta}{sub 6}, {beta}{sub 9,10}, {gamma}{sub 1,5}, {gamma}{sub 6,8}, {gamma}{sub 2,3}, {gamma}{sub 4}), have been evaluated for elements with atomic number 36 {<=} Z {<=} 92 at incident photon energies ranging E{sub L1} < E{sub inc} {<=} 200 keV using currently considered to be more reliable theoretical data sets of different physical parameters, namely, L{sub i} (i = 1-3) subshell photoionization cross sections based on the relativistic Hartree-Fock-Slater model, the X-ray emission rates based on the Dirac-Fock model, and the fluorescence and Coster-Kronig yields based on the Dirac-Hartree-Slater model. At incident photon energies above the K-shell ionization threshold, the contribution to the production of different L X-ray lines due to the additional L{sub i} (i = 1-3) subshell vacancies created following decay of the primary K-shell vacancies have also been included in the present calculations. The important features pertaining to dependence of the tabulated intensity ratios on the incident photon energy and atomic number have been discussed.
