X-Ray Rayleigh Scatting Method for Analysis of Heavy Atoms in Low Z Media

“…The change in flux at each energy is determined by the change in the corresponding scattering probabilities. For Compton scattering Equation 1 may be rewritten as: P (9, E)c -N (9, E) da "'(a),• (5) where N is Avogadro's number, p is the mass density of the material, ca is the fraction of the total weight comprised by the i,b type atoms, Z and A are respectively the atomic and mass numbers of the ith type atoms, and the summation is again taken over all the atoms present in the molecular structure of the material. Similarly for Rayleigh scattering, Equation 1 may be rewritten: (6) where K is the complete coefficient of Z3 in Equation 4, representing a constant for a specified angle and primary energy.…”
