Study of the hydrogen diffusion in superlattices by grazing angle neutron reflectometry

Surface oxide on thin films of yttrium hydride studied by neutron reflectometry

“…NR for characterization of hydrogen in thin films and multilayers of metal hydrides was first reported in 1993 by Mâaza et al 8 . Later, Munter et al showed how deuterium absorption could be monitored in-situ during loading experiments on thin Pd films 9,10 .…”

In situ neutron-reflectometry measurements of hydrogen and deuterium absorption in a Pd/Nb/Pd layered film

“…3 Several techniques have been applied to the study of the hydrogen content in metals: volumetric measurements, 4 resonant nuclear reaction analysis, 5 recoil reaction measurements, 6,7 x-ray diffraction, 3,8 nuclear magnetic resonance, 9 neutron scattering, and neutron reflectometry. 10,11 The majority of these methods do not provide depth distributions of hydrogen, however. The techniques most commonly used to study hydrogen profiles are resonant nuclear reaction analysis 5 and elastic recoil measurement.…”
