Excerpt
Introduction and Nomenclature: The elastic scattering of photons is one of the fundamental modes of interaction of photons with matter and has been an object of vigorous investigations for quite a long time. The tables of precise elastic scattering cross sections for any element and for varying photon energies have long been needed not only from the point of view of this importance in fundamental science but also from the point of view of their applications in various fields such as material study, health physics, biology, medicine, etc. Such tabulated values of differential elastic scattering cross sections are available for elements? In recent years, a numerical method to estimate Rayleigh scattering amplitudes (the elastic scattering of photons hy bound electrons which is predominant in the energy region of our interest) within an accuracy of the order of 1% has been developed. At the present time this happens to be the state-of-the-an method for estimating the most precise cross sections.
