Lantanides' Experimental L X-ray Fluorescence Cross Sections at 9 keV and 12 keV with Synchrotron Radiation

Type: article
Abstract: Experimental determinations of L x-ray fluorescence cross sections for elements with 64 ≤ Z ≤ 70 at 9 keV and 12 keV were carried out with synchrotron radiation. The experimental setup provided a linearly polarized monoenergetic photon beam producing a very low background, which improved the signal to noise ratio and reduced the experimental uncertainties. Results of the experimental cross sections obtained for the L lines were grouped considering the transitions scheme, the energies of the emission lines and the detector's resolution. The data obtained were compared with theoretical data using two different data tables. A very good agreement was found between our experimental values and the theoretical values calculated using Puri's data. A new set of ω L1 , f 12 and f 13 coefficients for Gd were also used to calculate theoretical cross sections and the experimenal values are in excellent agreement with them.
