Braggs reflections

  1. May 12, 2009 #1
    1. The problem statement, all variables and given/known data
    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_


    2. Relevant equations



    3. 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).
