Mössbauer Diffraction. II. Dynamical Theory of Mössbauer Optics

The dynamical theory of M\"ossbauer optics is developed utilizing the multiple-scattering equations derived in the preceding paper (I). The general optical equations obtained are analogous to the equations of the dynamical theory of x-ray diffraction, but are generalized to account for the very strong polarization mixing which occurs in M\"ossbauer optics. This polarization mixing leads to a number of interesting features, such as Faraday effects, selective absorption, and selective critical reflection. The cases of Bragg reflection, Laue transmission, critical reflection, and off-Bragg transmission are treated in detail.
