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

Öz

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 Ultra-LEGe detector. The
measured experimental values have been compared with theoretically and
empirically (only for M-shell average fluorescence yields) calculated values of
pure elements.
