J Phys Condens Matter. 2011 Mar 16;23(10):105303. doi: 10.1088/0953-8984/23/10/105303. Epub 2011 Feb 21.

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.
