Inelastic Neutron Scattering and Lattice Dynamics of Novel Compounds

Using a combination of lattice dynamical calculations and inelastic neutron scattering experiments, we have studied the phonon properties of a variety of solids. The materials studied find a wide range of applications, which include the negative thermal expansion materials and other technologically important samples, and also geophysically relevant minerals. Often we have made it possible to pr...

Molecular Dynamics Calculation of Neutron Inelastic Scattering from Water*

The data generated by a molecular dynamics calculation on liquid water at 1 gm CM-3 and 10 °C have been used to simulate a neutron inelastic scattering experiment on water. It is shown that already at K '' 1 A-i the function w 2Snc(K, w)/K 2 i5 a good replica of the spectrum of proton velocity autocorrelation . It is emphasized that the separation of (K, o) into quasielastic and inelastic parts...

Soil Carbon Measurements Using Inelastic Neutron Scattering

Soil carbon sequestration is a whole new area of energy related research that provides a fundamentally new approach for dealing with climate change resulting from the substantial increase in CO2 concentration in the atmosphere. Carbon sequestration in soil is recognized to play a major role in allowing fossil fuels to remain a vital component of the national energy mix. At present soil carbon i...
