Broken halo revels all
Article Abstract:
The study of the properties of the nuclear halo in 19C using radioactive nuclear beams shows that the halo is formed by the spreading out of the outermost neutron from the 18C core. According to the uncertainty principle, the outermost loosely bound neutron after moving away from the core can stay there for a long time. The properties of the halo nuclei depend on the pairing attraction of the loosely bound neutrons and the models used to study them are based on the quantum mechanical system.

Neutron halo slips
Article Abstract:
Some of the most neutron-rich of these nuclei have a diffuse neutron cloud that extends to large distances beyond the compact nuclear core. The halo extends to such a large radius, and its coupling to the target nucleus is so strong, that the nuclei finally coming into contact at the fusion-barrier radius are most likely to be the core of the projectile nucleus and a target nucleus that has already 'eaten and digested the halo neutrons.

The nucleon in a spin
Article Abstract:
Two experiments designed to measure the spin structure of the neuron yielded varying results. The first experiment conducted by the Spin Muon Collaboration used a target containing frozen, polarized deuterons and yielded an In value of -0.08 +/- 0.06. On the other hand, Stanford scientists used a polarized helium-3 nuclei and yielded an In of -0.022 +/- 0.011. The latter value is more accurate since more data were used in measurement.
