Measurement of L X-ray fluorescence cross-sections for elements with 45 ⩽ Z ⩽ 50 using synchrotron radiation at 8 keV

Abstract

The L shell fluorescence cross-sections of the elements in range 45 ⩽ Z ⩽ 50 have been determined at 8 keV using Synchrotron radiation. The individual L X-ray photons, Ll, Lα, Lβ I, Lβ II, Lγ I and Lγ II produced in the target were measured with high resolution Si( Li) detector. The experimental set-up provided a low background by using linearly polarized monoenergetic photon beam, improving the signal-to-noise ratio. The experimental cross-sections obtained in this work were compared with available experimental data from Scofield [1,2] Krause [3,4] and Scofield and Puri et al. [5,6]. These experimental values closely agree with the theoretical values calculated using Scofield and Krause data, except for the case of Lγ, where values measured of this work are slighter higher.
