Calculation of Rayleigh Scattering (Coherent) Cross Section in Aluminum

Abstract

In this paper the Rayleigh scattering cross section in aluminum has been calculated, through atomic scattering factor calculation, using Wave function involves The independent of the particles approximation for the values , And for the incident Photon energy range from 620 eV ( to 12.4 KeV ( , 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 , 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
