Experimental determination of ruthenium L-shell fluorescence yields and Coster–Kronig transition probabilities

Abstract

The L-shell fluorescence yields and the Coster–Kronig factors of ruthenium (and the corresponding uncertainty) were determined for the first time experimentally by applying radiometrically calibrated instrumentation of the Physikalisch-Technische Bundesanstalt. The resulting fluorescence yields (ω_L3 = 0.0459(20), ω_L2 = 0.0415(26), ω_L1 = 0.0109(9)) and the Coster–Kronig factors (f₂₃ = 0.177(32), f₁₃ = 0.528(90), f₁₂ = 0.173(73)) agree reasonable well with parts of the data from the literature.
