text: Since the neutron and proton spins can be either parallel (for a total of $1$) or antiparallel (for a total of zero), there are four ways to couple $s_n$, $s_p$, and $l$ to get a total of $1$: (a)
text: The force depends on whether the spins of the nucleons are parallel or antiparallel, as it has a non-central or tensor component.
