5.96 keV Enerjide Hg, Pb and Bi Elementlerine ait Bileşiklerin Ortalama M Kabuğu Floresans Verimlerinin Araştırılması ve 70Yb ile 92U Arasındaki Elementlerin Ortalama M Kabuğu Floresans Verimlerinin Deneysel Olarak Hesaplanması

Çalışmada 70Yb elementinden 92U elementine kadar olan saf elementler için ortalama M kabuğu floresans verimleri deneysel olarak hesaplanmıştır. Elde edilen veriler, teorik atomik yapı hesaplamaları için ve malzeme karakterizasyonunda kullanılan spektroskopik yöntemler için daha çok veri sağlayacaktır. Ve ayrıca, M kabuğuna ait ortalama floresans verimler Hg, Pb ve Bi elementleri içeren bileşikler için 5.96 keV’de M kabuğu X-ışını üretim tesir kesitleri kullanılarak hesaplanmıştır. Bileşikler 1.85 GBq 55Fe radyoaktif kaynağı ile uyarılmıştır. Uyarılmış numuneden yayınlanan M kabuğuna ait X-ışını fotonları Ultra LEGe dedektörü ile sayılmıştır. Kimyasallardaki elementlerden elde edilen veriler literatürde yer alan ve çalışmada deneysel olarak hesaplanan değerlerle karşılaştırılmıştır.

The Determination of M Shell Average Fluorescence Parameters From 70Yb to 92U and of Hg, Pb and Bi Compounds Using 5.96 keV Photons

In this study, the empirical average M shell fluorescence yields were calculated from 70Yb to 92U. These obtained values will supply more experimental data for theoretical estimations of atomic structure calculations and spectroscopic analysis which is used for material characterization. And also, chemical effects on average M-shell fluorescence yields for Hg, Pb, and Bi compounds were determined using M X-ray production cross-sections at 5.96 keV photon energy. The samples were irradiated using a 1.85 GBq 55Fe radioactive source. M X-rays emitted by samples were counted using a multi-channel analyzer with a UltraLEGe detector. The measured experimental values have been compared with theoretically and empirically (only for M-shell average fluorescence yields) calculated values of pure elements.
