摘要：

In this work the dependence of the anomalous absorption of X-rays on the crystal thickness and temperature gradient value was studied. The refracted and reflected beams intensities, as well as their sum intensities were measured for crystal thicknesses in the range of 0.3-4.5 mm. Significant increase in the sum intensity of the refracted and reflected beams is observed in presence of temperature gradient. It is shown that the anomalous absorption in the crystal in presence of the temperature gradient is decreased and this effect is stronger expressed in thick crystals.
