Measurements of Coster-Kronig Enhancement Factors for Yb, Lu, Os and Pt Elements

Abstract

In this work X-ray production cross-sections' measurements, L(l), L(alpha), L(beta) and L(gamma), 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. (C) 2009 Elsevier Ltd. All rights reserved.
