Abstract

Using radiometrically calibrated instrumentation of Physikalisch-Technische Bundesanstalt, the L-shell fluorescence yields and Coster-Kronig factors of tantalum (including the uncertainty budget) were experimentally determined based on transmission and X-ray fluorescence experiments. The determined fluorescence yields (ωL3=0.247(12)\omega_{L3} = 0.247(12), ωL2=0.278(15)\omega_{L2} = 0.278(15), ωL1=0.157(12)\omega_{L1} = 0.157(12)) were independently validated trough XRR-GIXRF experiments. Both, the Coster-Kronig factors (f23=0.123(84)f_{23} = 0.123(84), f13=0.328(152)f_{13} = 0.328(152), f12=0.14(11)f_{12} = 0.14(11)) as well as the fluorescence yields are in good agreement with the most established databases in the field of X-ray fluorescence.
