An older PRL, but certainly worth a read. Ginocchio shows the underlying symmetry for a phenomenon thought to be a coincidence. The relationship he finds between spatial amplitudes of pseudospin degenerate wavefunction doublet components (discussed in detail in other papers) is elegant. A significant result is employing this symmetry can removed the need for a tensor component in NN interactions.

Chiral three-nucleon interaction and the carbon-14 dating beta decay, Holt et al.
