In the interaction of X-rays with materials, some of the x-rays will be absorbed, and some will be transmitted or diffracted through the material listed in Table 1205. The degrees of absorption/fluorescence, Compton and Rayleigh scatter and transmission depends on:
         i) X-Ray energy
         ii) Sample thickness
         iii) Materials density
         vi) Materials composition.

Table 1205. Interaction of X-ray with materials.

Rayleigh scatter, Diffracted X-rays Scattering without loss of energy (re-radiate waves with the same frequency), from bound charges, coherent scatter X-ray diffraction (XRD)
Compton scatter Scattering with loss of energy, from loosely bound charges, incoherent scatter  
Fluorescence When absorption occurs X-ray fluorescence (XRF)
Transmitted X-rays Direct transmission  
Auger electron Electron ejected from atoms by absorbing energy from X-ray Auger electron spectroscopy (AES)
Photoelectrons Emitted electrons X-ray photoelectron spectroscopy (XPS)
