Cross-sections for the production of Ll, Lα, Lβ and Lγ x-rays in 22 elements (57 ≤ Z ≤ 92) by photons of 13 different energies in the range 8-50 ke V are reported. The experimental values of the cross-sections were determined by measuring the absolute yield of L subshell x-rays emitted from a target of a given element and thickness when it was bombarded with a known flux of photons of given energy. The theoretical values of the cross-sections were calculated from the theoretical/semi-empirical values of subshell photoionization cross-sections, fluorescence yields, Coster-Kronig transition probabilities, intra-shell transition probabilities and radiative decay rates. The present and previous measured and calculated values of the cross-sections are tabulated to bring out the existing status of L x-ray production cross-sections.
