Angular Dependence of L_α/Ll, Lα/Lβ and Lα/Lγ X-ray Intensity Ratios of Lead at 59.54 keV Photon Energy

L_α/L_l, L_α/L_β and L_α/L_γ x-ray intensity ratios of lead have been calculated at an angular range 85˚-135˚ at 59.54 keV photon energy by using a Si (Li) detector. The results showed that the L_α/L_β and L_α/L_γ intensity ratios decreased as the scattering angle increased. The correlations between the L_α/L_β and L_α/L_γ intensity ratios and scattering angles were also high. On the other hand the variation of L_α/L_l intensity ratio with the scattering angle is irregular.
