The Li, Lalpha, Lbeta and Lgammax-ray production cross-sections in four elements with Z ranging from 66 to 72 at seven different energies in the interval 8.265-11.730 keV were measured. Experimental measurements were carried out on a few elemental samples to examine the effect of Coster-Kronig transitions on fluorescence cross-sections for the L x-ray line using an Si(Li) detector system with an energy resolution of 160 eV at 5.96 keV x-ray energy. Absolute values of L x-ray cross-sections were calculated with incorporation of the enhancement due to the Coster-Kronig effect for these elements. The measured enhancement factors are smaller than predicted by theory. Copyright (C) 2003 John Wiley Sons, Ltd.
