原始语种摘要: The behavior of hydrogen in metals has attracted considerable attention in fundamental and applied research areas for many decades. Among metals, palladium is remarkable because it can absorb large quantities of hydrogen, and hydrogen atoms are highly mobile in the fcc Pd lattice. The dynamics of hydrogen in Pd have been investigated by neutron spectroscopy, which is the best tool to provide insights into the microscopic dynamics of hydrogen atoms. As for a bulk system, the phonon dispersion relations and atomic vibrations of hydrogen were successfully measured by inelastic neutron scattering. The jump diffusion processes among interstitial sites Pd lattices were also confirmed by quasielastic neutron scattering. The above observations were reconciled with theoretical calculations...
