Influence of the chemical environment changes on the line shape and intensity ratio values for La, Ce and Pr L lines spectraPorikli, SevilAmericiumChemical environmentEnergy shiftExperimental spectraGaussian functionsIdentical conditionsIntensity ratioLine positionsLine shapePolynomial functionsRelative intensitySi detectorsCeriumWe measured the energy shifts and relative intensities of Lα, Lβ and Lγ components in 26 elements under identical conditions using Si(Li) detector and 241Am as the source of excitation. The purpose of these measurements was to characterize the dependence of the line position and line width with the chemical environment changes. The spectra were fitted by Gaussian functions and the background was removed from the experimental spectra using a polynomial function. The present intensity ratio values are in good agreement with the data of Scofield [1]. The values measured by Erturul [2] show a similar behavior but somewhat higher. © 2011 Elsevier B.V.
