Measurements of L-shell X-ray production cross sections for Sn and Sb using 6–14 keV synchrotron radiation

Abstract

The synchrotron radiation induced Lkk=l,η,α,β1,3,4,6,β2,15,9,10,γ1,5,γ2,3,4 X-ray production cross-sections (XRPCS) have been measured for Sn and Sb at energies ranging 6–14 keV. These present measured Lk XRPCS have been compared with different sets of theoretical cross sections calculated using the Dirac-Fock (DF) model based X-ray emission rates, the non-relativistic Hartree-Fock-Slater (HFS) model based photoionization cross-sections and three sets of fluorescence and Coster-Kronig (CK) yields based on the Dirac-Hartree-Slater (DHS) model, the semi-empirical values tabulated by Krause, and the recently reported experimental values. The present measured Lk XRP cross sections for Sn and Sb are found to differ by up to 25% from different sets of presently calculated values. Further, the average L-shell fluorescence yields (ω¯L) have been deduced from the present measured total L XRPCS using the theoretical photoionization cross sections and are compared with the values available in literature.
