(Think about the plot of f vs sin(theta)/lamda). The f" contribution to anomalous scattering of F(000) is 0, just in contrast to that the real part in this (000) direction is the full number of electrons; i.e., electron does not anomalously scatter in this (000) direction. So, the phase of (000) stays safely at 0, or the symmetry-broken Friedel's law is broken (F000.ne.F-0-0-0). [...][log in to unmask] |
