Measurement of mass attenuation coefficients by Si(Li), NaI(Tl) and Cd(Tl) detectors
(Transworld Research Network, 2012-01-01)
Mass attenuation coefficients of the some elements were
determined for two photon energies using different three detectors.
The samples were irradiated using 10 mCi Cd-109 and 100 mCi
Am-241 radioactive point sources. ...

Determination of K shell absorption jump factors and jump ratios of 3d transition metals by measuring K shell fluorescence parameters
(Elsevier Ltd., 2015-01-01)
Energy dispersive X-ray fluorescence technique (EDXRF) has been employed for measuring K-shell absorption jump factors and jump ratios for Ti, Cr, Fe, Co, Ni and Cu elements. The jump factors and jump ratios for these ...
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 ...
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 ...
