TL;DR: The authors report the results of the experiment E142 which measured the spin dependent structure function of the neutron, which confirms the fundamental Bjorken sum rule with O({alpha}{sub s}{sup 3}) corrections to within one standard deviation, a major success for perturbative Quantum Chromodynamics.
Journal ArticleDOI
Neutron Imaging Technique for In Situ Measurement of Water Transport Gradients within Nafion in Polymer Electrolyte Fuel Cells
TL;DR: In this paper, the authors used neutron radiography to measure water gradient profiles within Nafion{reg_sign} in an operating polymer electrolyte fuel cell (PEFC) in order to optimize the PEFC performance.

TL;DR: For the kinematic range of $0.014lxl0.7$ and $1l{Q}^{2}l17(\mathrm{GeV}/c{)}^{2] 2, this article reported a precision measurement of the neutron spin structure function using deep inelastic scattering of polarized electrons.

TL;DR: In this article, the first moments of the polarized valence quark distributions were determined by the Bjorken sum rule and the NLO results were used to determine the Q2 dependence of the ratio g 1 F 1 and evolve the experimental data to a constant Q2 = 5 GeV2.
