Representation and tabulation of spherical atomic scattering factors in polynomial approximation

Abstract

It is recommendable to use an analytical expression to compute the atomic scattering factor. Out of several possible analytical notations one is chosen where ln f ( s ) is represented by a polynomial expression. For three most common radiations (Cu, Mo, Ag) the available data of the International Tables were converted into seven coefficients per ion. A list of these coefficients is provided.
