    For molibdenium

    We see from the PT that Mo is a BCC material, so the face diagonal [011] has 2⋅(12) atoms over a distance of 2√a.

    The value of the lattice parameter a can be found in the same manner as the previous problem (noting that the BCC structure has only 2 atoms per unit cell rather than 4). Thus,
