Özet

In this study K-alpha 1, K-alpha 2 and KLL Auger line widths were determined semi-empirically by using K shell fluorescence yields of sulfur even if K-alpha X-ray lines cannot be resolved in our detector system. The samples of 1,2,4-Triazoles were irradiated by an annular 50 mCi Fe-55 radioactive source. It was found that halogens (e.g. Cl) and electron donating groups (e.g. -CH3, -OCH3, -OH etc.) have a crucial effect onto the valence shell structure of sulfur. The expansion of Auger line widths was attributed to the Coster-Kronig transitions in L shells which are energetically possible. (C) 2018 Elsevier B.V. All rights reserved.
