    • We use the third term in his Eq. (13), ignoring the magnetic (electron spin) term. The electron momentum operator P vec is transformed to a position operator r vece and the plane-wave phases are expanded to first-order in this position. The expression may be derived from the Kramers-Heisenberg formula discussed by J. J. Sakurai, Advanced Quantum Mechanics (Addision-Wesley, Reading, MA, 1967).
