With major new investments in infrastructure for neutron science in the US, Europe, Asia, and Australia either completed or in advanced planning, our capabilities for understanding new materials using...
Constraining the neutron-neutron scattering length with \eftnopi
neutron-neutron scattering length
2011/7/20
We compute a model-independent correlation between the difference of neutron-neutron and proton-proton scattering lengths |a(nn)-a^C(pp)| and the splitting in binding energies between Helium-3 and tri...
Itinerant Spin Excitations in SrFe2As2 Measured by Inelastic Neutron Scattering
Itinerant Spin Excitations Inelastic Neutron Scattering
2010/11/23
We report inelastic neutron scattering measurements of the magnetic excitations in SrFe2As2,
the parent of a family of iron-based superconductors. The data extend throughout the Brillouin
zone and u...
The effect of the pseudogap on suppressing high energy inelastic neutron scattering in superconducting YBa2Cu3O6.5
pseudogap high energy inelastic neutron
2010/11/18
We have measured the spin fluctuations in the YBa2Cu3O6.5 (YBCO6.5, Tc=59 K) superconductor
at high-energy transfers above 100 meV.Within experimental error, the momentum dependence is
isotropic a...
Neutron scattering study of a quasi-2D spin-1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure
Neutron scattering study hydrostatic pressure
2010/11/17
We report inelastic neutron scattering study of a quasi-two-dimensional S=1/2 dimer system
Piperazinium Hexachlorodicuprate under hydrostatic pressure. The spin gap becomes softened
with the incre...
A Direct Measurement of the Neutron-Neutron Scattering Length
the Neutron-Neutron Scattering Length free neutrons
2010/10/15
A direct measurement of nn-scattering by colliding free neutrons has never been performed. Indirect measurements continue to provide inconsistent results, leaving the issue of charge symmetry in the n...
