The nucleon in a spin.

Examines results of two independent experiments to make measurements of the spin structure of the neutron, the twin particle of the proton. The CERN experiment performed by the Spin Muon Collaboration (SMC); The experiment at the Stanford accelerator in California which used a gas target of polarized helium-3 nuclei; Use of deep in-elastic scattering in both experiments to probe the interior of the neutron; Conclusion; More.
