Introduction to Small Angle Neutron Scattering
Small Angle Neutron Scattering, SANS
Most scientists and engineers are familiar with light scattering, which occurs when light encounters differences in refractive index. Light scattering is used to obtain information about material structure, composition, and dynamics. Perhaps less familiar is neutron scattering, which occurs when neutrons encounter differences in neutron scattering length density. Neutron scattering can be used to characterize optically opaque materials (e.g. concrete and crude oil) and provides scattering in absolute units. Here, I will discuss some of the theory and applications behind small angle neutron scattering (SANS), which is useful for characterizing length scales from 1 nm to 150 nm and dynamics from minutes to days. I will focus primarily on my own SANS experiments on nanoscale emulsions.
