Small-angle neutron scattering (SANS) measurements have been performed to investigate deuteride particle morphology and the phase transformation temperature hysteresis in low-concentration Nb–D alloys. Deformation either by cold rolling and or by previous deuteride cycling induced a coarse deuteride particle distribution. This observation is attributed to a more heterogeneous precipitation proc...

ND band state D+ ions are treated as a sum over pairs. The wave functions of a D+ pair is assumed to be a product of a Bloch function in lattice space times a Bloch function in separation space. Overlap allows a strong force fusion reaction to 4He++. A coupling between the nuclear change and the ion charge distribution in the lattice is described. The change in ion charge distribution scatters ...

The deuteride ~hydride! precipitation and decomposition microstructure in single-crystal Pd has been investigated in a series of in situ small-angle neutron scattering ~SANS! measurements. The particle morphology along the absorption and desorption branches of the 353-K pressure-composition isotherm are consistent with a loss of particle coherency, leading to the formation of large, micron-thic...

The controlled out-diffusion method was employed to induce a nuclear reaction in a palladium (Pd) plate with a MnOx film. The time-resolved mass spectra for Pd deuteride revealed tritium (T) production during the outdiffusion experiment. Similar time behaviors of mass number 1-4 and 6 in the spectra was also observed for Pd hydride. Film blackening was observed for most Pd deuteride as well as ...

Vibration-rotation and pure rotational data in the X2Σ+ ground state and electronic data from the A2Π – X2Σ+ and B2Σ+ − X2Σ+ transitions of CaH and CaD were used in the quantum-mechanical direct-potential-fit (DPF) analysis to determine an analytic potential energy function for the X2Σ+ ground state of CaH, and a radial correction function for the CaD isotopologue. The potential energy function...

Very few hydride complexes are known in which the metals have a high-spin electronic configuration. We describe the characterization of several high-spin iron(II) hydride/deuteride isotopologues and their exchange reactions with one another and with H2/D2. Though the hydride/deuteride signal is not observable in NMR spectra, the choice of isotope has an influence on the chemical shifts of dista...

The ruthenium hydride of (Ar(4)CpOH)Ru(CO)(2)H exchanges cleanly and rapidly with D(2) at room temperature to generate the ruthenium deuteride. A chain mechanism is proposed to explain the much more rapid exchange of RuH/D(2) than RuCO exchange with (13)CO.

Measurements of nuclear spin relaxation times over a wide temperature range have been used to determine the interaction energies and molecular dynamics of light molecular gases trapped in the cages of microporous structures. The experiments are designed so that, in the cases explored, the local excitations and the corresponding heat capacities determine the observed nuclear spin-lattice relaxat...

In order to find the signature of multi-body fusion, experiments of ion-beam implantation were carried out using titanium deuteride target made by the gas-loading method. Up to now, charged particles that are not known in the ordinary beam-target interaction have been observed in the experiment.[1,2,7]

A twin system for hydrogen-isotope absorption experiments has been constructed to replicate the phenomenon of heat and He generation during D2 gas absorption in nano-sized Pd powders reported by Arata and Zhang, and to investigate the underlying physics. For PdZr oxide nano-powders, anomalously large energies of hydrogen isotope absorption, 2.4 0.2 eV/D-atom and 1.8 0.4 eV/H-atom, as well as...
