Neutron Reflectometry,ickness. The high sensitivity of neutrons to hydrogen and deuterium enables NR to detect absolute hydrogen concentrations in the at.% range even in nm-thick layers. Therefore, NR is an ideal tool to study in-situ the hydrogen/deuterium absorption and desorption properties of thin films on a nanomete

Neutron Imaging,drogen compared to those of elements or isotopes, respectively, in usual structural materials like steels or zirconium alloys allows the detection even of small amounts of hydrogen in such materials. The dependence of the total macroscopic neutron cross section of the sample or component on the hydr

Incoherent Neutron Scattering,n. Cambridge University Press, New York, 2012). This strong incoherent scattering removes neutrons from a transmitted beam, so that hydrogen-rich regions appear as dark spots in neutron radiographs. The scattered neutrons are spread into all directions and appear as a contribution to the background

Inelastic and Quasi-Elastic Neutron Scattering,provide an understanding of the vibrations and diffusion of hydrogen and deuterium in the host lattice. The techniques are then illustrated using typical hydrogen storage materials. Incoherent inelastic scattering can be applied to isolated hydrogens—where the protons can be modelled as in an isolat

Elastic Recoil Detection Analysis,recoil nuclei moving under the impact of the ions of the beam. This technique is well suited to light elements profiling, especially for hydrogen measurements which can be performed with usual helium-4 beams available in most facilities. This chapter presents an overview of ERDA main features and fo

Nuclear Reaction Analysis,centration can be quantified absolute and the method can provide depth profiles in the range up to 2–3 μm with a depth resolution in the range of a few nm. Concentrations of 500 at. ppm are easily measurable and with special efforts sensitivities down to 1 ppm have been achieved. The chapter describ
