Nearest Neighbor Distances

Simulation result using NPT Molecular Dynamics and the Lennard-Jones Potential Full MATDL record

Each atom in a FCC lattice has an equivalent nearest neighbor environment. In the simplest case of hard spheres of diameter σ arranged in a FCC lattice, each sphere has:

  • 12 nearest neighbors at a distance of σ
  • 6 second nearest neighbors at a distance of \sqrt 2 \sigma
  • ? third nearest neighbors at a distance of \sqrt 3 \sigma
  • 12 fourth nearest neighbors at a distance of
