Please solve this question completely and in a (correct) way as soon as possible and in its entirety. An accurate solution, without explanation. I just want the mathematical solution (solid state physics) to give you a very good evaluation.
Question Nine: (5 points) Consider a line of atoms o bond length of af/2. T o, with an form factors are: f, for atom and fi for atom o. The incident beam of x-rays is perpendicular to the line of atoms. a) Write down the general form of the structure factor (Sa): b) Find the possible values of the structure factor (S) for the above lattice: c) Write down the proportionality relation between the intensity of the diffraction peak and the structure factor:
