Neutron scattering from concentric cylinders. Intraparticle interference function and radius of gyration

Abstract

A theoretical model to describe the scattering behaviour of concentric cylinder colloidal particles has been developed. In particular, equations are given for the intraparticle form factor and the radius of gyration determined by neutron scattering. It is shown that both of these quantities are strongly dependent on the coherent scattering length density of the solvent medium. From the analysis, the dimensions and average coherent scattering length density of the colloid particle can be determined.
