Dynamical theory of Mössbauer diffraction in the presence of hyperfine interaction for TRBD-geometry are developed. We show that “dispersion surfaces interaction” must be taken into account by exact solution of boundary condition if χ > 10 -4. We fined out that the oversurface diffracted wave intensity reaches maximum value at ϑ ∼ ϑ c and reveal an unusual angular dependence.
