Further, the theoretical scattering cross sections were calculated by a numerical integration in intervals of 0.01[degrees] using form factor and incoherent scattering functions along with the Thomson scattering cross section and Klein-Nishina cross sections in the integrand, respectively (see Hubbell et al.
