Structure factor of a simple cubic crystalA simple cubic crystal has one atom per unit cell. The electron density in a unit cell can be described by a gaussian n(r) = Aexp(-2.5×1021r²). Here r is measured in meters. The lattice constant is 0.2 nm. What is the ratio of the structure factors S(111)/S(000)?. |
