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 ...
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 ...

The anisotropy parameter values β of the L shell fluorescent X-rays (Lι (L3-M1), Lβ6 (L3-N1), Lα1,2 (L3-M5,4) and Lβ2,15 (L3-N5,4) of Bi, Pb, Ta, Lu, and Yb excited by 22.6 keV photons were measured. These values were used ...
Why Do We Need Nuclear Energy in Turkey?
(IPCAP 2016, 2016-02-27)
Nuclear energy is the energy in the nucleus, or core, of an atom. This energy can be released as heat from a chain reaction in a radioactive element such as uranium. Although Turkey has rich uranium reserves, Turkey has ...
Study of absorption parameters around the K edge for selected compounds of Gd
(Wiley, 2016-02-11)
The K shell absorption jump ratios, jump factors, effective atomic numbers, and electron densities were derived from the measured
total mass attenuation coefficient using an energy dispersive X-ray fluorescence spectrometer ...
