Abstract

The emission of X-rays in K_a and KLL Auger energy
regions were analyzed for transition metals by using energy dispersive X-ray
fluorescence (EDXRF) system. To acquire more information in this energy region,
the semi-empirical determination of K_a, Auger line-widths
and the L sub-shell level widths were performed. Since K shell is a core shell
for transition metals and it is not easily be affected by valence shell
electronic distributions, K shell fluorescence yields were used for the
semi-empirical determinations. In the experiment, elemental form of transition
metals were excited by 59.5 keV g-rays from ²⁴¹Am annular source and the emitted  X-ray photons were counted by Ultra-LEGe
detector with a resolution of 150 eV at 5.9 keV. The obtained results were
compared with the other studies in the literature
