# Proton-Neutron Lattice as a form of matter?

Would it be possible for a lattice of protons and neutrons (I'm picturing a plane of hexagons in my head) to exist bound by the strong nuclear force (not gravity)? I know that the strong force losses its power when an atomic nucleus gets to be too large, but in a lattice, it would only have to bond one proton to a few neutrons or one neutron to a few protons at a time. Would this work? If so, what would be the properties of such a material?

the potential energy of the repulsion goes like $1/r$, but the number of protons repelling you goes like $r^2$ (surface area of the sphere.) $1/r *r^2 = r$ so the energy density blows up horribly. –  BebopButUnsteady Apr 26 '12 at 19:43
