Phonon spectra of ordered PdCuH and PdAgH produced under a high hydrogen pressure

Research output: Contribution to journalConference articlepeer-review

Abstract

Atomically ordered PdAgH and PdCuH hydrides synthesized in an atmosphere of gaseous hydrogen at P = 3 GPa were studied by inelastic neutron scattering. The results showed a large difference the Pd-H, Ag-H and Cu-H interactions. Values of 93 and 116 meV were predicted for the local H vibrations in dilute Ag-H and Cu-H solid solutions.
