Webwith coherent scattering (see above), whereas if the electron is ejected from the atoms, the scattering is (incoherent) Compton scattering. At high energies, the total Compton cross … WebThe average scattering length is. b = abc + (1 − a)bd, and the average incoherent cross section can be calculated by an average over the isotope abundances: σinc 4π = (δb)2 = a(bc − b )2 + (1 − a)(bd − b )2 = a(1 − a)(bc − bd)2. This means that we see an incoherent scattering due to the isotope mixture, strongest at 50%-50% ...
