Abstract
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 to determine the kinematic coefficient ratios α(Lι/Lα1,2), α(Lι/Lβ6), and α(Lα1,2/Lβ2,15). The Lι and Lβ6 X-rays were found to be anisotropically emitted whereas Lα1,2 and Lβ2,15 X-rays showed less anisotropic spatial distributions. Also, the polarization degrees of Lι and Lα X-rays were measured for the present elements and observed that the Lι lines were found to be strongly polarized whereas the Lα lines showed less polarization.
