Experimental determination of L fluorescence yields of gadolinium
Résumé
The fluorescence yields are useful X‐ray atomic fundamental parameters for X‐ray spectrometric purposes but suffer from large tabulated uncertainties, and this is the first time to our knowledge that all three subshell parameters are measured together. We determined the three L partial fluorescence yields and the associated Coster‐Kronig transition probabilities of gadolinium, by selectively ionizing the three L subshells with a tunable monochromatic photon beam. We found ω 1 = 0.099(3) , ω 2 = 0.162(4) , and ω 3 = 0.159(3) that are in good agreement with tabulated values, but our derived uncertainties are significantly reduced.
