The rare earth nuclei from N=92 to N=108 display a very regular pattern of empirically extracted interactions of the last protons with the last neutrons. The simplicity of the empirical systematics suggests that a simple interpretation should be possible. We discuss calculations of these proton-neutron (p-n) interactions with a zero-range {delta} force.
