cell in terms of a. 14 0) Show that every edge of the Wigner-Seitz cell for the BCC lattice has the length V2a14, where a is the lattice constant of the BCC structure. (b) Show that the two diagonals on each face of the Wigner-Seitz cell for the FCC latice are in the ratio V2:1
2) The primitive translation vectors of a hexagonal space lattice of parameters a and c are given by -; (53i+j) (-53i+j) PCR a- Find the volume of the unit cell, primitive cell and Wigner-Seitz cell. b. Show that the reciprocal lattice has also hexagonal symmetry with parameters c , then calculate the volume of a primitive cell in the reciprocal space (vr).
