Show that a diffuse scattering intensity from two arbitrary atoms i and j of an amorphous solid (spatially isotropic) can be written sin(Krij) I=j" Krij where rij is the distance between atoms i and j. b) Assume spherically symmetric electron density n,(r) associated with an atom i and show that atomic form factor can be written sin(Gr),2dr /n(r) sin(Gr). fi = 47 n:(r) Gr What is the maximum limit for fi? What are the physical conditions (realistic or non-realistic) to obtain the maximum limit during scattering?
