This is the basis of the modern density functional approach.

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.
