The semi-empirical determination of KLL Auger, K α1 and K α2 X-ray line widths for sulfur atom in new 1,2,4-triazol compounds containing thiophene ring

摘要

In this study Kα1, Kα2and KLL Auger line widths were determined semi-empirically by using K shell fluorescence yields of sulfur even if KαX-ray lines cannot be resolved in our detector system. The samples of 1,2,4-Triazoles were irradiated by an annular 50?mCi55Fe 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.
