A perturbative derivation shows that X-ray-optical nonlinear signals in crystals carry a band-structure contribution, the joint density of states, separable from atomic-scale Wannier function contributions by polarization.
The differ- ence ˜I+(˜εid)− ˜I− (˜εid) also exhibits a very distinctive peak near the band gap energy
