title: Diffusion studies in the type-B kinetics regime using neutron reflectometry and isotope multilayers.
abstract: Neutron reflectometry in combination with isotope multilayers is an advanced method to determine ultra-low diffusion lengths and self-diffusivities in solids. An approach is presented which allows the extraction of volume self-diffusivities from reflectivity patterns in nanocrystalline materials in the type-B kinetics regime.
