Influence of Substitutional and Interstitial Impurities on Local Hydrogen Modes in Nb
Neutron vibrational spectroscopy has been used to study the association of H with interstitial (O) and substitutional (V) defects in a Nb host. From these results we propose a model for the site occupancy of H bound by O at low temperatures.
