Question

CsCl has an ordered body centred cubic crystal structure with the Cs atom at position 0,0,0 and the Cl atom at position ½, ½, ½ in the unit cell. State the general rules for the CsCl structure factor. List the Miller indices of the planes from which a diffracted beam is produced up to (320). Given that the atomic scattering factor for Cs is 1.5 times that of Cl, indicate which diffracted beams will be visible in an x-ray diffraction experiment and whether they will be strong or weak.
