Way in which atoms or ions (considered as hard spheres) pack together to fill space. In BCC packing, the spheres in Layer A are separated slightly and the spheres in Layer B are offset so that they fit into the depressions between atoms in Layer A. Each sphere is touched by eight neighbors, four in the layer below and four in the layer above.
