Darwin–Prins dynamical diffraction: Takagi-Taupin coupled Helmholtz; Pendellösung oscillation

Layer 1 — Physicsin the x-ray-physics subtree

Darwin-Prins dynamical-diffraction framework — the canonical replacement for the kinematical Bragg approximation when x-ray wavefields in perfect crystals traverse multiple Bragg planes coherently (Darwin, Phil. Mag. 27, 315, 1914; Prins,…
