Abstract

The theory of the reflecting properties of multi layer neutron monochromators is reviewed. It is shown that both the Bragg reflection and the mirror reflection can be understood, at least qualitatively, within the familiar kinematical theory of neutron scattering. For a detailed quantitative understanding of these phenomena, including such questions as the optimum number of bilayers, the effect of the multiple reflection that is neglected in the kinematical theory must be taken properly into account. The way in which this can be done using the dynamical theory of neutron scattering is indicated.
