How is structure factor calculated?

How is structure factor calculated? Definition The structure factor \mathbf{F}_{hkl} is a mathematical function describing the amplitude and phase of a wave diffracted from crystal lattice planes characterised by Miller indices h, k, l. \mathbf{F}_{hkl} = F_{hkl}\exp(i\alpha_{hkl}) = \sum_j f_j\exp[2\pi i (hx_j + ky_j + lz_j)] How do you determine the structure factor of a […]
