Study of The X-ray Coherent Scattering Cross Section of Copper

Abstract In this study the coherent scattering function ƒ(k) has been calculated for x-ray in Copper using the Wave function involving Slater’s roles approximation for the values 0 ≤ k ≤ 1.6 A0-1, The Rayleigh scattering cross section, has been calculated. The Rayleigh scattering cross section was found to be dominate at low energy, where the scattering cross section starting from very small energy and less than 1KeV, Also the increasing of angular distribution for Rayleigh scattering cross section is principle dependent on the value of atomic scattering factor f(k), and observed Rayleigh scattering decreasing at high energies, while it is more distinct at low energies, for this reason the Rayleigh scattering is very important at low energies, because the scattering angle is large.
