Quasielastic Neutron Scattering from α-AgI

1978
In this contribution we will present new experimental quasielastic neutron scattering data on α-AgI along with an interpretation of these data in terms of a simple model+. As has already been discussed in the introductory part of this session, α-AgI may be visualized to a first approximation as a sea of mobile silver ions within a rigid b.c.c.

Quasielastic neutron scattering and super-protonic conductors

Solid State Ionics, 1993
Abstract The present “state of art” of quasielastic incoherent neutron scattering (QINS) methods is reviewed, with special emphasis on the analysis of experiments concerning the diffusive motion of protons in solid-state protonic conductors. Models for uncorrelated and correlated diffusion, including local and long-range aspects of the motion are ...

Quasielastic neutron scattering by hydrogen in transition metals

Berichte der Bunsengesellschaft für physikalische Chemie, 1972
AbstractThe quasielastic scattering of slow neutrons by hydrogen in metals is a sensitive method for the investigation of the diffusion process on an atomistic scale. First a review of the theory of the quasielastic neutron scattering by hydrogen in metals is given. Then some methods to measure the quasielastic scattered neutrons are discussed.

Dynamics of surface water in ZrO2 studied by quasielastic neutron scattering

The Journal of Chemical Physics, 2004
A quasielastic neutron scattering experiment has revealed the dynamics of surface water in a high surface area zirconium oxide in the temperature range of 300–360 K. The characteristic times of the rotational (picoseconds) and translational (tens of picoseconds) components of diffusion motion are well separated. The rotational correlation time shows an

Quasielastic Neutron Scattering and Solid State Diffusion

2000
Abstract The book provides an account of quasielastic neutron scattering (QENS) which has made many important contributions to the atomistic elucidation of diffusion processes in solids. The unique feature of QENS is that it probes the diffusion process on atomistic scales of space and time simultaneously.
