Evidence for H (D) Ordering in PdHx (PdDx)
Abstract
Resistivity, annealing, and neutron-diffraction studies of PdHx and PdDx provide evidence for ordering of the H and D atoms on the octhaderal interstitial sublattice. Neutron diffraction results on a PdD0.76 single crystal indicate that the D atoms order on the fcc interstitial lattice with every fifth (4,2,0) plane vacant and all others filled, corresponding to the Ni4Mo structure.
