Incoherent scattering of x-rays
WebWhen the X-ray is incident onto a crystal surface, its angle of incidence, θ, will reflect with the same angle of scattering, θ. And, when the path difference, d is equal to a whole number, n, of wavelength, λ, constructive … 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.
