Kα and Kβ x‐ray fluorescence cross‐sections were experimentally determined for elements in the range 26 ⩽ Z ⩽ 40 at various excitation energies using and x‐ray tube with a secondary exciter system as the excitation source. The x‐ray tube with a secondary target arrangement was used to obtain high intensity with a high degree of monochromatization. Experimental values were compared with the theoretical values calculated using I Kβ / I Kα ratios based on Hartree—Fock and Hartree—Slater theories. The experimental values for all the elements at various excitation energies were in good agreement with the theoretical values.
