Source sentences:
text: The force depends on whether the spins of the nucleons are parallel or antiparallel, as it has a non-central or tensor component.
text: The spin-dependence of the forces follows also from the fact that ud diquark can be constituent of nucleon (and occupy the place at the center of nucleon) only when spins of both quarks are parallel.
