Measurements of Coster–Kronig enhancement factors for Yb, Lu, Os and Pt elements

In this work X-ray production cross-sections’ measurements, Lι, Lα, Lβ and Lγ, of Yb, Lu, Os and Pt elements have been studied at energies in the range 9.572–14.384 keV and the effect of Coster–Kronig transitions on fluorescence cross-sections for L X-ray line has been obtained. From these studies absolute values of L X-ray cross-sections have been calculated with incorporation of the enhancement due to the Coster–Kronig effect. The experimental enhancement factors tend to be smaller than those predicted by theory.
