D = Γα²/6 applies to any diffusing species in any cubic lattice. Show that this is true for vacancy diffusion in a pure FCC metal. (hint: consider two adjacent {111} planes and determine what fraction of all possible jumps result in the transfer of a vacancy between the two planes. Is the same result obtained by considering adjacent {100} planes?
