Neutron inelastic cross section measurements for natTi

EPJ Web of Conferences, 2017
A neutron inelastic scattering experiment was performed at the GELINA (Geel Electron LINear Accelerator) neutron source of the European Commission Joint Research Centre Geel (EC-JRC Geel) with the aim of determining the reaction cross sections for the ...

Elastic and inelastic scattering of neutrons on 238U nucleus

EPJ Web of Conferences, 2014
Advanced modelling of neutron induced reactions on the 238U nucleus is aimed at improving our knowledge of neutron scattering. Capture and fission channels are well constrained by available experimental data and neutron standard evaluation.

Phonon dispersion curves in Cr2AlC single-crystals

Materials Research Letters, 2018
Neutron inelastic scattering is used for the first time to measure phonon dispersion branches in Cr2AlC MAX phase single crystals with appreciable size. Phonon spectra are also calculated within the Density Functional Perturbation Theory (DFPT) framework

Inelastic Scattering of Cold Neutrons [PDF]

Nature, 1951
THE gain of energy of cold neutrons on being scattered by crystalline materials has been investigated with a beam of lead-filtered neutrons from the Harwell pile. The maximum energy of the neutrons in the beam was 0.0026 eV. and the mean energy was 0.0017 eV. The experimental arrangement is shown in the accompanying diagram. The counter and sample were

Neutron spin structure from polarized deuteron DIS with proton tagging

Physics Letters B, 2019
Polarized electron-deuteron deep-inelastic scattering (DIS) with detection of the spectator proton (“tagged DIS”) enables measurements of neutron spin structure with maximal control of nuclear effects.

Instrumental aspects

EPJ Web of Conferences, 2017
Every neutron scattering experiment requires the choice of a suited neutron diffractometer (or spectrometer in the case of inelastic scattering) with its optimal configuration in order to accomplish the experimental tasks in the most successful way. Most
