The angular distribution of fast charged particles originating at the lattice sites is studied by computer simulation. Multiple scattering effects were found to be necessary for agreement with the experiment in the planar case. The dependence of the intensity of multiple scattering on crystal thickness and temperature is discussed. Detailed calculations of the blocking pattern are performed for the [100] and [111] directions of a simple lattice (b.c.c.). It is shown that in case of emitting nucleus displacement from the lattice site the most sensitive parameter of the distortion is the value of the originating planar shoulder near a lowindex direction. The distortion of the blocking pattern is calculated as a function of the compound nucleus lifetime.
