Calculation of Coster-Kronig Enhancement Factors of the Some Elements in the Atomic Number Range 50 ≤ Z ≤ 59

Abstract

L X-ray fluorescence cross-sections of some elements in the atomic number range 50 <= Z <= 59 have been calculated theoretically according to subshell excitation energies of elements. The Coster-Kronig transitions (f(12); f(23), and f(13)) are non-radiative transitions. The Coster-Kronig enhancement factors due to the effect of the Coster-Kronig transitions on L X-ray fluorescence cross-sections have been calculated theoretically. The calculated values have been compared with other earlier experimental and theoretical values.
