Measurement of L subshell fluorescence yields for high-Z elements excited by 22.6keV photons
(Elsevier Ltd., 2012-03-01)
The σ L1, σ L2 and σ L3 subshell X-ray production cross sections for U, Th, Bi, Pb, Tl, Hg, Au, Pt, Os, W, Ta, Lu, Yb and Er have been measured at 22.6keV incident photon energy. The measurements were performed using a ...
Determination of K shell absorption parameters for some lanthanides using the X-ray attenuation method
(nrcresearch press, 2015-07-27)
The total attenuation cross section at the K edge, absorption jump ratio, jump factor, Davisson–Kirchner ratio, and oscillator strength parameters for the K shell were determined by measuring the total attenuation cross ...
The excitation probabilities of Kα,β and Lα1,2 for some elements in 56≤Z≤68 at 59.54 keV
(Elsevier, 2016-02-01)
The Kα,β and Lα1,2 excitation probabilities for some elements in 56≤Z≤68 at 59.54 keV were obtained using a Si(Li) detector with a multichannel analyzer. It is the first time that the Kα,β and Lα1,2 excitation probabilities ...

Studies on effective atomic numbers, electron densities from mass attenuation coefficients near the K edge in some samarium compounds
(Elsevier Ltd., 2015-07)
The effective atomic numbers and electron densities of some samarium compounds were determined using the experimental total mass attenuation coefficient values near the K edge in the X-ray energy range from 36.847 up to ...
Measurements of K shell absorption jump factors and jump ratios using EDXRF technique
(2015-04-10)
In the present work, the K-shell absorption jump factors and jump ratios for 30 elements between Ti (Z = 22) and Er (Z = 68) were measured by energy dispersive X-ray fluorescence (EDXRF) technique. The jump factors and ...
