Abstract
L x-ray fluorescence cross-sections for elements with 45 ≤ Z ≤ 50 were measured at 7 keV using synchrotron radiation photoionization. The experimental set-up provided a linearly polarized monoenergetic photon beam producing a low background and improving the signal-to-noise ratio. The data obtained for the L lines, Ll, Lα, LβI, LβII, LγI and LγII, were grouped considering the transition scheme, the energies of the emission lines and the detector resolution. Results for the experimental cross-sections obtained were compared with theoretical values using two different data tables. In general, it was found that the experimental fluorescence cross-sections are slightly higher (7–10%) than the theoretically calculated data and in some cases these differences are up to 40%.
