... A neutron of spin ½ interacts with a nucleus of spin I to form two states in which the spins are either parallel or antiparallel. The combined spin J of these states is J = I + ½ and J = I – ½, respectively. Different scattering lengths (amplitudes) b+, b– are associated with these states. The proba ...
