  Expanding a double tetrahedron formation of equal spheres arranged in fcc
structure correlation between the positions of the nucleons and quantum numbers
has been detected. The number of protons in the structure is not simply
consistent with all the corresponding quantum numbers but also bears the same
physical meaning as in quantum mechanics. The detected correlations between
lattice positions of the protons and quantum numbers raise the possibility the
solid nuclear structure might be able to provide an explanation for the single
particle properties of the nuclei.
