Chemical effects on Lα/Lβ X-ray intensity ratios of Ba, La and Ce

X-ray fluorescence spectrometry

“…Other applications included work by Leiro and Heinonen 530 on Ka 1.2 X-ray emission spectra of KCl as well as metallic Ca, Fe and K. A Doniach±Sunjic type line shape was used to ®nd Lorentzian tails for the spectra. Chemical effects on La : Lb intensity ratios of Ba, Co and La were studied by Baydas et al, 531 with experimental values compared with theoretical values of pure elements. To complete this paragraph, your reviewer returned to another published work from the Kyoto group, 532 where extended ®ne structure in characteristic XRF was demonstrated for Al.…”

Measurement of absorption edge parameters near K edge for the compounds of Zn, Zr, Cd, Ba and Pb

“…Here, it is reported that the variation in the mass attenuation coefficient of these studied elements is due to the change in oxidation state of the elements. Various workers have studied the effect of chemical environment on the K shell intensity ratios [5][6][7], L shell/subshell intensity ratio [8][9][10][11][12], K/L shell fluorescence yield [13][14][15][16] and production cross-sections [17] for different elements and their compounds from periodic clear that all these parameters are affected with the change in chemical structure or chemical nature of the given elements to its compounds due to its nearby lying ligands.…”

Chemical Shifts of Kα and Kβ1,3 X-ray Emission Spectra for Oxygen Compounds of Ti, Cr, Fe, Co, Cu with WDXRF

“…Xray emission and absorption processes have been used in a large number of analytical techniques for investigations of many kinds of materials. Since the early days of x-ray spectrometry, the K / K x-ray intensity ratio and x-ray fluorescence crosssections for elements has been extensively studied (Baydas E., Ekinci N., Büyükkasap E., ahin Y., 2002;Küçükönder A., ahin Y., Büyükkasap E., and Kopya A. I., 1993;. In our earlier studies we investigated chemical effects Baydas E., Sö üt Ö., ahin Y., ve Büyükkasap E., 2002;Bayda E., 2005; using a Si(Li) detector with resolution 160 eV at 5.9 keV.…”
