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...

Inelastic Neutron Scattering Study of Mn12-Acetate

We report zero-field inelastic neutron scattering experiments on a deuterated powder sample of Mn12-Acetate consisting of a large number of nominally identical spin-10 magnetic clusters. Our resolution enables us to see a series of peaks corresponding to transitions between the anisotropy levels within the spin-10 manifold. A fit to the spin Hamiltonian H = −DS z − μBB · g · S −

Inelastic magnetic neutron scattering in CePd3

We have performed time-of-flight neutron scattering measurements on a single crystal of the intermediate valence compound CePd3. At 10K, a Kondo-esque inelastic magnetic scattering peak occurs near DE 1⁄4 60meV with maximum intensity for momentum transfer Q near the ð 2 ; 1 2 ; 0Þ zone boundary. Spectral weight is transferred to lower energy as Q varies until at zone center the intensity at 60m...

Ultra-High Resolution Inelastic Neutron Scattering

Two types of ultra high energy resolution neutron scattering instruments, the backscattering spectrometer and the spin echo spectrometer, are described. Examples of the types of research which can be done with these instruments are given and plans for a cold neutron backscattering spectrometer which will be built in the NIST Cold Neutron Research Facility (CNRF) are discussed. It is hoped that ...
