of these collisions are very small, the emitted neutrons are very close to the axis of the emerging beam. This process is thus referred to as Small Angle Neutron Scattering (SANS) In the animation below

distance distribution. To prove this, it is enough to deform a metal sample placed in an X-ray or neutron beam.

but the descending portion shows the presence of oscillations resulting from interference between beams reflected by the two surfaces. The size of these oscillations is related to the layer thickness. The
