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 ...
