Abstract
The vibrational density of states (DOS) of hydrogen trapped at dislocations in deformed PdH0.0008 has been measured at 4 and 295 K with incoherent inelastic neutron scattering. The vibrational DOS at 4 K exhibits features characteristic of the low-temperature ²-Pd hydride phase, while the characteristic peak in the 295 K DOS corresponds to the solid solution ±-Pd phase. This is evidence of a ±'² transition at low temperature within the distorted environment of dislocations.Citation
