Notes:
The local environment of an "origin'' sphere in an assembly of spheres may be represented by a Voronoi polyhedron or by a polyhedron of simplicial lines. These figures may be projected on to a spherical surface of contacts1 and this representation is used here to examine the number of spheres of one diameter which can be packed regularly in contact with an origin sphere of the same or other diameters. The restriction that in the packings the spheres contacting the origin sphere also make contact with all their neighbor spheres in the contacting shell allows only 15 configurations in the range of radius K (radius of origin sphere/radius of contacting sphere), 0.225〈K〈8.8. The relationship of two of these configurations and the possible structure of the C60 molecule is examined. The reason why a previous model of random close packing produced answers which agreed well with experimental values only for some values of K is revealed.
