Scattering is a general term for several physical processes in which radiation of some sort changes direction due to an interaction with a particle. Scattering can be classified by the type of radiation (ie, electromagnetic, x-ray, neutron), or by the relative sizes of the wave and the particle (ie, Rayleigh, Mie, geometric).

SAXS vs. X-ray diffraction?
Small-angle X-ray is a device to investigate the structure near the surface (1-100 nano-meters). The x-ray is a high penetrating measurement for the structure of whole crystal structure. Therefore, lo …

Can I write the scattering condition in this form?
Q: But It looks like a particle will always going to scatter in some other direction. Is this correct?
Generally, yes if the wave vector $\vec k$ is not ended on the boundary of the first Brillouin z …

How does phase coherence length depend on elastic collisions?
The elastic scattering relaxation time $\tau_{el}$ comes in this expression through the diffusion constant $D$, which is again nothing to do with the dephasing process. …

If the net electric field inside a conductor is zero, how did alpha-particles deflect in Rut...
For Rutherford's back scattering experiment, it is a microscopic theory. The electric field experienced by an $\alpha$ particle is in an atomic scale. …
