Recent studies on the transmitting and focusing properties of capillary optical systems have shown that several unexpected effects take place during the experiments. One such effect is a decrease in the beam divergence behind the capillary structures. In this letter, we present results on x-ray scattering at grazing angles inside capillaries. During x-ray propagation in capillary channels, there is a strong angular redistribution of the beam, which has been explained in the framework of the wave scattering theory.
