Small angle neutron diffraction method permits the observation of large scale structures with clusters (particles) size from 1 nm to 100 nm. From the properties of the Fourier transform, [4], it follows that the diffraction intensity from objects of this size is concentrated in a small angle region, 0.2 < (9 < 10 radians, in the so-called zero peak. In conventional diffractometers the zero peak is inseparable from the instrumental broadening of the incident neutron beam. To make the measurement possible, SANS method applies cold neutron sources and filtration of the incident neutron flux by mirror guides or Be filters. In SANS, the angular interval Q < I sin QR/QR) in (2) is practically constant...

Information on the conformations of polymer chains in amorphous polymers has been obtained by using small-angle neutron diffraction. The technique involves measurement of the coherent scattering of neutrons by mixtures of deuterated and protonated polymer molecules. Analysis of the scattering data leads to an estimation of the radius of gyration (Section...
