Evaluation of thermal neutron scattering law of nuclear-grade isotropic graphite [PDF]

EPJ Web of Conferences
Graphite is a candidate of moderator in innovative nuclear reactors such as high-temperature gas-cooled reactors and molten salt reactors. Scattering of thermal neutrons by a moderator material has a significant impact on the reactor core design.

Dynamics of cubic-tetragonal phase transition in KNbO$_3$ perovskite

, 2004
The low-energy part of the vibration spectrum in KNbO$_3$ was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong diffuse scattering, which consists of two components. The first one is quasi-

On the Extraction of the Neutron Spin Structure Functions and the Gerasimov -- Drell -- Hearn Integral from $^3\vec {He}(\vec e, e')X$ data

, 1996
Nuclear effects in polarized inelastic electron scattering off polarized $^3He$ are discussed; in the kinematics of future experiments at CEBAF, Fermi motion effects are found to be much larger than in deep inelastic scattering.

Magnetic excitations in the low-temperature ferroelectric phase of multiferroic YMn2O5 using inelastic neutron scattering [PDF]

, 2011
We studied magnetic excitations in a low-temperature ferroelectric phase of the multiferroic YMn2O5 using inelastic neutron scattering (INS). We identify low-energy magnon modes and establish a correspondence between the magnon peaks observed by INS and ...

Thermal neutron scattering data for 7LiF and BeF2

EPJ Web of Conferences, 2017
Based on the coherent elastic, incoherent elastic, coherent inelastic and incoherent inelastic scattering processes, a code named SIRIUS is developed to produce thermal neutron scattering data for crystals in ENDF-6 format. The phonon band structures and

Quasi-elastic neutron scattering in the high-field phase of a Haldane antiferromagnet

, 2001
Inelastic neutron scattering experiments on the Haldane-gap quantum antiferromagnet NDMAP are performed in magnetic fields below and above the critical field Hc at which the gap closes.

Neutron Structure Function and A=3 Mirror Nuclei [PDF]

, 2000
We investigate deep inelastic scattering from He-3 and H-3 within a conventional convolution treatment of binding and Fermi motion effects. Using realistic Faddeev wave functions together with a nucleon spectral function, we demonstrate that the free ...

Spin dynamics of the ferromagnetic superconductor UGe$_{2}$

Inelastic neutron scattering was used to study the low energy magnetic excitations of the ferromagnetic superconductor UGe$_{2}$. The ferromagnetic fluctuations are of Ising nature with a non-conserved magnetization and have an intermediate behavior ...

Nucleon Structure Functions and Nuclear DIS

, 2004
The nucleon structure study in nuclear deep inelastic scattering is considered. It is shown that nuclear data provide a new source of information about dynamics of parton distributions in the nucleon.
