Neutron quasielastic scattering by (CH3NH3)5Bi2Cl11

Physica B: Condensed Matter, 1997
Abstract (CH3NH3)+-cation rotation in crystalline (CH3NH3)5Bi2Cl11 was studied by the QNS. The following (no doubt simplified) models were considered: 1. 1. All cations are equivalent and rotate as a whole around C-N axes 2. 2. Majority of cations behave as in point (1) and the remaining ones do not move (for the neutron observation window).

Quasielastic neutron scattering in condensed oxygen

Physica B: Condensed Matter, 1992
The quasielastic spectra of liquid and plastic-crystalline oxygen are shown to be dominated by the magnetic response. An approximate separation of the nuclear and magnetic responses from the total, unpolarized neutron double differential cross-sections is achieved by means of a subtraction of the structural contributions calculated from a Molecular ...

Point-Defect Diffusion from Coherent Quasielastic Neutron Scattering

Physical Review Letters, 1985
We outline a theory which suggests that the dynamics of point defects in crystals can be studied by coherent quasielastic neutron scattering. The theory assumes that the surrounding lattice distortion follows each defect instantaneously, and that the distortion fields of different defects can be linearly superposed.

Dynamics of collagen hydration by quasielastic neutron scattering

Physica B: Condensed Matter, 2000
Abstract QENS spectra from 52% H 2 O-hydrated collagen fibres ( T =276–321 K) were modelled by three-component scattering laws including small central peak broadenings. These give diffusion coefficients for mobile H 2 O of ∼5×10 −6  cm 2 /s, with activation energy ∼2 kcal/mol. The broad components relate to localised modes.
