ABSTRACT

Lα, Lβ, and Lγ X-ray fluorescence cross sections for Ho and Yb have been measured at various incident photon energies in the energy range 16.04 ≤ E ≤ 24.68 keV. The measurements have been done using an X-ray tube with a secondary-excitor system of Zr, Nb, Mo, Cd, and In. The experimental values of the cross-sections were determined by measuring the absolute yield of L subshell X-rays emitted from a standard target of a given energy. Theoretical tabulated values of subshell photoionization cross-sections, fluorescence yields, Coster-Kronig transition probabilities and radioactive decay rates have been used to calculate the theoretical values of the cross-sections. The experimental results of the cross-sections at various excitation energies have been compared with theoretically calculated values. Fairly good agreement is obtained between the present experimental results and the calculated values.
