Abstract
The application of the spin-echo small angle neutron scattering (SESANS) technique for structural characterization of interacting colloidal suspensions is considered in this work. The framework to calculate the theoretical SESANS correlation function is briefly laid out. A general discussion regarding the features of SESANS correlation functions obtained from different model systems is presented. In comparison with conventional elastic scattering tools operation a the same length scale, our mean-field calculations, based on monodisperse spherical colloidal system, show that the real-space measurement provided be SESANS presents a powerful probe for studying the intercolloid potential. The reason of this sensitivity is discussed from the standpoint of way, in which how the spatial correlations are manifested in different neutron scattering implementations. This study leads to a better understanding regarding the distinction between SANS and SESANS.
