Can anomalous (f') and dispersive (f") contributions be ignored?
I know this was not at all your point, but are these the right terms? I thought both f' and f" were called anomalous--or better, resonant--contributions, whereas dispersive contributions are due to different amounts of resonant scattering at different wavelengths, say "peak versus inflection." Jacob
