A quantum-mechanical calculation of the scattering rate of light by light in the polarizable medium of a plasma is carried out. It is shown that if the frequency ?0 of the incident light is much greater than the electron plasma frequency ?p, the ?A2 term in the nonrelativistic Hamiltonian coupling the radiation to matter dominates the j.A interaction, provided the frequency shifts ?? satisfy ??<
