Kristina Verdal, Terrence J. Udovic, John J. Rush, Ronald L. Cappelletti, Wei Zhou
Rapid reorientational motions of the B12H122- icosahedral anion, a key intermediate in borohydride dehydrogenation, are revealed by quasielastic neutron scattering (QENS) measurements of Cs2B12H12 between 430 K and 530 K. At 430 K, over the range of

Quasielastic neutron scattering study of hydrogen motion in NbC(0.71)H(0.28)

In order to study the mechanism and parameters of H jump motion in the nonstoichiometric Nb carbides, we have performed quasielastic neutron scattering (QENS) measurements for NbC(0.71)H(0.28) over the temperature range 11- 475 K. Our results indicate that

The Nature of Deuterium Arrangements in YD3 and other Rare-Earth Trideuterides

September 30, 2008
Author(s)
Terrence J. Udovic, Qingzhen Huang, Antonio Santoro, John J. Rush
The efficacy of different structural models for describing the observed neutron-powder-diffraction (NPD) measurements of bulk polycrystalline YD3 as well as other hexagonal rare-earth (i.e., Nd, Tb, Dy, Ho, Er, and Tm) trideuteride powders has been
