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.

TL;DR: The neutron longitudinal and transverse asymmetries have been extracted from deep inelastic scattering of polarized electrons by a polarized $^3$He target at incident energies of 19.42, 22.66 and 25.51 GeV.
Journal ArticleDOI
Laser Polarized Muonic Helium
N. R. Newbury,A. S. Barton,P. Bogorad,Gordon D. Cates,M. Gatzke,Brian Saam,L. Han,R. Holmes,Paul Souder,J. Xu,D. Benton +10 more
TL;DR: Laser techniques to polarize targets of muonic helium are developed and it is planned to use these targets to measure the spin dependence of nuclear muon capture.
Journal ArticleDOI
Highly polarized muonic He produced by collisions with laser optically pumped Rb.
A. S. Barton,P. Bogorad,Gordon D. Cates,H. Mabuchi,H. Middleton,N. R. Newbury,R. Holmes,J. McCracken,Paul Souder,J. Xu,Dale Tupa +10 more
TL;DR: Highly polarized muonic helium is formed by stopping unpolarized negative muons in a mixture of unpolarization gaseous He and laser polarized Rb vapor and forms muonic He ions which are neutralized and polarized by collisions with Rb.
