This is the basis of the modern density functional approach.

Recent experimental progress in diffraction made the measurement of charge and magnetization densities in crystalline solids possible, with an accuracy at least as good as theoretical accuracy. Theoretical developments of the m

In the case of interest in this lecture the radiation field is a beam of neutrons and the non-uniform potential is provided by the non-uniform magnetic field inside a magnetic material.

Its formulation in Becker-Coppens treatment is only phenomenological, but has the advantage that the integrated intensity P becomes proportional to the structure factor when the extinction parameter x.→ ∞.

We can best display the hierarchy of density matrices and their final profection onto various “islands of experiment” in Fig. 1, borrowing from the Dick Weiss’ delightful model.
