Probing depth with GiSANS and near surface SANS
Understanding quantitatively grazing incidence scattering is important for the technique to be widely used to evaluate structure in interfacial layers. Model structures from well-characterised particles present a simple means to test principles. The penetration depth of evanescent waves should depend on the incident angle (strictly the difference between Qz and the critical Q). Initial data has shown an expected dependence of the width of Lorentzian profiles for Bragg rods. The present proposal is to test this relation further by exploring different size particles.
