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 ... -
Determination of K-shell absorption jump factors and jump ratios for La2O3, Ce and Gd using two different methods
(2015-02-01)The K shell absorption jump factors and jump ratios for La2O3, Ce and Gd samples have been determined using the gamma or X-ray attenuation and EDXRF methods. It is the first time that the K shell absorption jump factor and ... -
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. ... -
Measurement of L subshell fluorescence cross sections and intensity ratios of heavy elements at 22.6keV
(Elsevier Ltd., 2011-06-01)The L X-ray fluorescence cross sections (σL1, σLα, σσLη, σLΒ, σLΒ6, σLΒ2,4,15, σLΒ1,3, σLγ, σLγ1, σLγ2,3,6,8, σLγ4,4' and σLγ5) and ILα/ILi (i=l, η, Β6, Β2,4,1,5, Β1,3, γ, γ1, γ2,3,6,8, γ4,4' and γ5 intensity ratios for ... -
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 L X-ray fluorescence parameters for Ho, Lu, W, Hg and Bi
(Elsevier Ltd, 2014-07-01)In this work, L X-ray fluorescence cross sections, L sub-shell fluorescence yields and level widths and radiative vacancy transfer probabilities of L sub-shells to Mi, Ni and Oi sub-shells were measured for the elements ... -
Measurement of magnetic quadrupole-electric dipole mixing ratios and angular distribution parameters in atomic inner-shell transitions
(Materials Science and Technology Conference and Exhibition 2013, MS and T 2013, 2013-10-27)In studies of the angular distribution of the magnetic L 3-subshell X-ray transitions it has been generally assumed that observed radiations consist of pure electric dipole transitions and contributions from higher-order ...
