Braggs reflections

  • #1

Homework Statement


How would you expect the intensities of the Bragg reflections in the x-ray diffraction patterns of cesium, cesium chloride and cesium iodide to compare? (The atomic numbers of cesium, chlorine and iodine are 55, 17 and 53 respectively_


Homework Equations





The Attempt at a Solution


I am really unsure how to do this question at all. The first part of this question delt with structure factors so I know that the scattering intensity I=Io A (S)^2 where S is the structure factor. Not sure how this helps?

The structure factor is proportional to the number of electrons in the atom (or the atomic number if the atom is uncharged).
