“…Although all of these processes are sometimes labeled jointly as Auger transitions, in our work we have followed the definitions presented in Refs. [37,39]. In the Auger contributions, the initial configuration hole is filled by an electron from a higher shell, and a second electron also from a higher shell is emitted to the continuum; in the Coster-Kronig contributions, the initial hole is filled by an electron from the same shell and the emitted electron belongs to a higher shell or to another subshell of the same shell.…”

Fluorescence yields (FY) for the Ni K and L shells were determined by a theoretical and an experimental group within the framework of the International Initiative on X-ray Fundamental Parameters (FPs) collaboration. CosterKronig (CK) parameters were also measured for the L shell of Ni. Theoretical calculations of the same parameters were performed using the Dirac-Fock method, including relativistic and QED corrections. The experimental values for the FY and CK were determined at the PTB laboratory in the synchrotron radiation facility BESSY II, Berlin, Germany, and are compared to the corresponding calculated values.

“…It can be achieved more studies about the M shell calculations or measurements using different irradiation source, different elements, different angles and different energy ranges [14][15][16][17][18][19][20][21][22][23]. Due to the complexity structure of M shell, the parameters were determined for pure elements and different energy ranges.…”

In this study, Mβα X-ray production cross-sections and average M-shell fluorescence yields were determined by using EDXRF at 5.96 keV for Pt, Au and Tl compounds. The photo-peak areas were used for the measurement of M X-ray production cross-sections and also other parameters. The obtained values were compared with the theoretical values in the literature to explain the changes in parameters. It was obtained that the changes were resulted from the electronegativity differences between Pt, Br and O in Pt compounds and Au, Br and O in Au compounds. As for Tl compounds, it was obtained different results and attributed to both of the charge transfer from one element to another and polarizability mechanisms of Tl. Öz Bu çalışmada, Mβα X-ışını üretim tesir kesitleri ve ortalama M kabuğu flüoresans verimleri 5.96 keV enerjide, EDXRF yöntemi kullanılarak Pt, Au ve Tl bileşikleri için belirlenmiştir. Foto-piklerin altında kalan alanlar M X-ışını üretim tesir kesitlerinin ve aynı zamanda diğer parametrelerin ölçülmesinde kullanılmıştır. Elde edilen değerler, parametrelerdeki değişimi açıklamak için literatürdeki teorik değerlerle kıyaslanmıştır. Değişimlerin Pt bileşiklerinde Pt, Br ve O arasındaki, Au bileşiklerinde ise Au, Br ve O elementleri arasındaki elektronegativite farkından kaynaklandığı belirtilmiştir. Tl bileşiklerinde ise değişimler hem bir elementten diğerine yük transferi hem de Tl elementinin polarize olabilmesi mekanizmalarına atfedilmiştir.
