WebMay 1, 1990 · The coherent and incoherent scattering are basically treated as competing processes and being such, to a . first-order approximation, f + S = Z. The approach starts with the assumption that the cross sections depend on the photon energy and scattering angle only through the single parameter q. WebWhen a photon interacts with an atom, a number of different absorption and scattering processes may occur. For an isolated atom at photon energies of less than 100 keV (the limit of most conventional X-ray generators), contributions to the total cross section come from the photo-effect, coherent (Rayleigh) scattering, and incoherent (Compton) scattering.

WebThe intensity at low q ($0.01 Å À1) varied as a quadratic function of P H and indicated a minimum value at P H = 30%, which can be explained by the scattering contrast between SP and SBR. The scattering intensity at high q ($0.3 Å À1 ) decreased with increasing P H , which is attributed to the incoherent scattering from hydrogen. Web9.01.3.3.4 Mean energy transfer.
