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 multipole terms have been overlooked. However, this assumption is questionable, especially in the case of heavy elements and high energies. In this study, by analysis of the angular distribution of the 22.6 keV photon induced X-ray transitions of U, Tl, Ta and Er the subshell alignment, the anisotropy parameters have been measured and from the measured parameters α kinematic coefficients, M2/E1 mixing ratios and polarization degrees have been deduced by energy dispersive X-ray fluorescence (EDXRF) system. The obtained results were compared with a few experimental and theoretical predictions available in the literature. Copyright © 2013 MS&T'13®.
