The Ll, Lα1,2, Ln, Lβ6, Lβ2,4,15,17, Lβ1,3,5, Lβ9,10, Lγ1, Lγ2,3,6,8, Lγ4,4′ and Lγ5 x-ray fluorescence cross-sections for U and Th were measured at 59.5 keV incident photon energy by using theoretical Li subshell photoelectric cross-sections, fluorescence and Coster-Kronig yields and fractional emission rates, and calculated theoretically by using atomic parameters. The measured values were compared with the theoretical values and experimental results available in the literature.

Incoherent scattering functions were determined experimentally for a photon energy of 59.5 keV at an angle 110° for the elements V, Cr, Co Br, Sr, Cd, I, Cs, Ba, Ce, Nd, Sm, Hf, Os and Tl using a high-resolution Ge(Li) detector. The experimental values of incoherent scattering functions at the momentum transfer x ≈ 2.74 Å-1 were compared with those estimated on the basis of the non-relativistic Hartree-Fock wavefunctions. The present results were in good agreement with those of Hubbell et al.
