This is a nontechnical Perspective commentary on two recent neutron scattering experiments (Science 326, 415 (2009) and Science 326, 411 (2009)) reporting evidence for the validity of a "Coulomb phase" description of the low-temperature…
We report results from an experiment measuring the semi-inclusive reaction $d(e,e'p_s)$ where the proton $p_s$ is moving at a large angle relative to the momentum transfer. If we assume that the proton was a spectator to the reaction taking…
