B 2.

3. The compound Cuprous Oxide (CujO) has a cubic conventional unit cell with the basis: 1. O: (0,0,0); (0.5,0.5,0.5) li. Cu: (0.25,0.25,0.25); (0.25, 0.75, 0.75), (0.75, 0.25, 0.75). (0.75, 0.75. 0.25) a. Sketch the conventional cell with this basis as best as possible b. Calculate the structure factor and show that certain diffraction peaks only depend on the Cu form factor (state the lattice type) and other reflections depend only on the O form factor (state the lattice type)
