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 β-Pd hydride phase while the characteristic peak in the 295 K DOS corresponds to the solid-solution α-Pd phase. This is evidence of a α→β transition at low temperature within the distorted environment of dislocations.
