Abstract
Diffraction of ultra-cold neutrons by the ordered supermolecular struc ture of polystyrene-polybutadiene-polystyrene block copolymer was theo retically and experimentally studied. Analysis of the diffraction data , obtained in experiments on the reflection of ultra-cold neutrons at a constant reflection angle and variable wave length (in the range lam bda > 5 nm), made possible the evaluation of volume-averaged parameter s of the supermolecular structure, such as the radius of polystyrene c ylinders, the angle of interplanar scattering, and the size of regions of coherence.
