Hello! This time I've got a question about the "Rayleigh-scattering" in X-Rays. The Rayleigh-scattering says, that the x-ray changes it direction only without "loosing" energy. Why does this happen and what has it to do with dipoles? My university professor told me, that the Rayleigh-scattering has something to do with dipoles. I can't find anything in books about that. I hope you could help me, that I can understand this problem. Thanks a lot!!
