Kinematic coefficient ratios, anisotropy parameters, and polarization degrees of L-3 X-ray transitions of Bi, Pb, Ta, Lu, and Yb

The anisotropy parameter values 13 of the I. shell fluorescent X-rays (Li (L-3-M-1), L beta(6) (L-3-N-1), L alpha(1,2) (L-3-M-5,M-4) and L-beta 2,L-5 (L-3-N-5,N-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 alpha(L iota/L-alpha 1,L-2), alpha(L-1/L beta(6)), and alpha(L alpha(1,2)/L beta(2,15)). The L-i and L beta(6) X-rays were found to be anisotropically emitted whereas L alpha(1,2) and L beta(2,15) X-rays showed less anisotropic spatial distributions. Also, the polarization degrees of L iota and L alpha X-rays were measured for the present elements and observed that the Li lines were found to be strongly polarized whereas the La lines showed less polarization.
