Abstract:
The contribution of scattering effects to the X-ray fluorescence intensity was studied for pure element samples, BaB binary samples and fused disk samples by theoretic calculation and experiment. Three scattering effects were considered in the present study, i. e. coherent scattering effect, incoherent scattering effect, and primary fluorescence that was scattered into the direction of detector. The study shows that the contribution of scattering effects to the intensity of fluorescence is related to the energy of the atomic absorption edge, and the sample's matrix. The higher the energy of the atomic absorption edge, the more the contribution of scattering effects to the intensity of fluorescence. The contribution of scattering effects to the fluorescence intensity is larger for light matrix samples than heavy matrix samples. The results of experiment show that the accuracy of theoretic calculation was evidently improved when the scattering effects were considered in the theoretic calculation for the intensity of fluorescence.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
