Detailed Description

This class implements Rayleigh (coherent, elastic) scattering, without support for polarization, at a higher level of fidelity than SmoothRayleighHelper: in addition to tabulated cross sections and atomic form factors, it uses tabulated real and imaginary anomalous scattering functions (indexed on atomic number) that account for the energy-dependent deviation from the smooth form-factor approximation near absorption edges. Below the energy range of the tabulated data, \(Z^2\) Thomson scattering is used instead.
