• Some experiences of multiple diffraction of neutrons by an aluminum crystal are described in this paper. The experimental conditions needed to assure that the results are treatable by the analytical methods developed earlier, are discussed. It was found that the Soller collimators are not adequate in this technique, as they do not limit the vertical divergence of the incident beam ; a new type of collimator, described in the text, had a notable result in the peak resolution. It is seen that the simultaneous differential equations cease to be valid, as expected, when the crystal approaches perfection, that is, in this context, when the mosaic angular spread η is lower than about 0.01°; then, the problem has to be treated dynamically.
