(A) G(r) for vivianite and AFEP. The G(r) decays rapidly with increasing r-values for AFEP, reflecting smaller coherently scattering domains than vivianite. (B) Zoom of lower r-values. Peak intensities for AFEP have been tripled (×3) so that small peaks are discernible. Subscripts: A for AFEP and V for vivianite.
