Neutron experiments give unprecedented look at quantum oscillations
October 23, 2012 — Researchers at the Department of Energy's Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator.
Beam Line 13 Fuels Discovery Fever for Fundamental Physicists
June 01, 2011 — Kucuker Dogan (left) and Matthew Musgrave prepare a helium-3 cooling cell that is used to measure the angle at which the neutron beam strikes the liquid hydrogen sample.
Fast Proton Hopping in Ice (Ih) Confirmed by Quasi-Elastic Neutron Scattering
June 01, 2011 — Protons (positive hydrogen ions) in an ice lattice have been “seen” to fast hop from one water molecule to another, using quasi-elastic neutron scattering at the SNS Backscattering Spectrometer, BASIS. This fundamental phenomenon that occurs at very low temperatures has important consequences for future investigations of proton conductivity in solids.
