Why are X-rays scattered by matter..?
1 Why are X-rays scattered by atoms in a material, though their frequencies are too high and for most of the atoms,electron clouds cannot respond to such a high frequency(that is before the electron cloud can reorient in the direction of electric field of X-ray, the field reverses,and consequently ,electrons do not respond to X-rays).
2 And even if the cloud does oscillate,it oscillates very very weakly and 180 degrees out of phase with the driving force,as the frequency of the driving force(electric field),in case of x-rays is much higher than resonant frequency of most atoms.
3 So,how is Thomson Scattering,in which electron cloud moves in phase with incident light and scatter light, possible in case of X-rays...?
I am attaching hereby a material for proof of the point 2 which I have mentioned here. In that material refer to the diagram on page 64 and also the diagram on page 65
