Diffraction condition

  1. Feb 19, 2009 #1
    What are the diffraction conditions for plans in a hexagonal closed packed lattice with atoms of the same type at 000 1/3 2/3 1/2?

    You mean the conditions for structure factor to be non-zero? These ones will depend on the basis as you seem to imply.
    Otherwise, the diffraction condition is given by Bragg's law, for any type of lattice.

    For close packed hexagonal I think that the structure factor is zero when h+2k is a multiple of 3.
