. STUDY OF THE SMALL ANGLE X-RAY X-ray

Electromagnetic radiation of extremely short wavelength (100 nanometres to 0.001 nanometre) produced by the deceleration of charged particles or the transitions of electrons in atoms.
 SCATTERING scattering

In physics, the change in direction of motion of a particle because of a collision with another particle. The collision can occur between two charged particles; it need not involve direct physical contact.
 DATA OF SOLIDS WITH TWO LENGTH SCALE STRUCTURE. A technique has been developed for using small angle x-ray and neutron scattering The term "Neutron Scattering" encompasses all scientific techniques whereby the deflection of neutron radiation is used as a scientific probe. It falls into two basic categories - elastic and inelastic scattering.  to study solids that are composed of systems of interacting scatterers. These solids have structure on two length scales that normally differ by a factor of at least 100; average diameters of the systems and the scatterers. The diameter is defined to be the longest distance separating two points in a scatterer. The new method makes use of an equation for analyzing the intensity of the small angle scattering from systems of interacting scatterers. The equation for the intensity takes account of the shapes and the diameter distributions of both the systems and the scatterers. With this technique, structure on length scales from 5 to l0,000 A can be investigated.
