Comparison of D- and H-cross-section anomalies in the non-metallic hydrides Y...
Improved experiments on the two non-metallic hydrides YH3 and YD3 are proposed. Since they have a well developed band gap in their electronic structure they are suitable as a... -
Intensity anomalies and momentum distributions in liquid and solid H2/D2.
H2 and D2 are simple systems which can be used to bench mark the accuracy of VESUVIO measurements. Previous measurements performed in 2008 indicate the presence of an intensity... -
Violation of y-scaling in D2 ¿ Test of existing theories
The applicants aim to perform the most authoritative measurements of NCS profiles by controlling and precisely quantifying everything to do with the sample. In July 2008 we... -
Proton/deuteron mobility in ammonium hexachlorometallates.
The piloting experiments RB820478, RB610497 and RB 10067 on VESUVIO on (NH4)2PdCl6 and (NH4)2TeCl6 have shown that: (i) at 300 K, the dynamics of NH4+ and PdCl6- and TeCl6- is... -
Copy of: Copy of: The Super Proton Conductors (H3O)SbTeO6 and Rb3H(SO4)2 ¿ Co...
Neutron Compton scattering (NCS) results will be obtained from the two super proton conductors (H3O)SbTeO6 and Rb3H(SO4)2, both powders. To facilitate direct comparison of... -
Vibrational density of states in ammonium hexachlorometallates.
The piloting VESUVIO experiments RB820478, RB610497 on (NH4)2PdCl6 and (NH4)2TeCl6 and RB 10067 on (ND4)2PdCl6 have shown that: (i) the H/D dynamics in NH4+/ND4+ is largely... -
Quantum heating effect in molecular hydrogen
The goal of this proposal for beam time on MARI (direct geometry) is to independently confirm (or refute) our observation using VESUVIO (indirect geometry) of a novel quantum... -
Onset of classical dynamics in ammonium hexachlorometallates.
The piloting experiment (RB 820239) on VESUVIO on (NH4)2PdCl6, has shown that, at 5 and 80K, H momentum distribution, J(y), in NH4+ is non-Gaussian with non-vanishing...
