abstract = {Symmetric Bragg-case reflections from a thick, ideally
imperfect, crystal slab are studied mostly by analytical
means. The scattering transfer function of a thin mosaic
layer is derived and brought into a form that allows for
analytical approximations or easy quadrature. The
Darwin-Hamilton equations are generalized, lifting the
restriction of wavevectors to a two-dimensional scattering
plane. A multireflection expansion shows that wavevector
diffusion can be studied independently of the real-space
coordinate. Combining analytical arguments and Monte Carlo
simulations, multiple Bragg reflections are found to result
in a minor correction of the reflected intensity, a moderate
broadening of the reflected azimuth angle distribution, a
considerable modification of the polar angle distribution,
and a noticeable shift and distortion of rocking curves},
