摘　　要：介绍了在Ru-200X光机上，采用Ag靶的韧致辐射谱，通过LiF晶体分光产生单色X射线，用Be、C材料作散射体，在6°-40°的方向上作散射测量。实验结果显示这两种低Z材料对X光散射具有方向性。给出了散射效率随散射角度的分布曲线，阐明这种方向性与X-射线能量E、散射体的原子序数Z和强散射角θ之间的关系。This paper introduces that experimental study to X-rays scattering in Be,C elements has been done through Ru-200 X rays generator. In the process of experiment, LiF crystal divides bremsstrahlung spectrum from Ag target into the hornochromatism X-ray, and the measurement angle is arranged from 6° to 40°. The measurement result shows that X rays scattering is of direction character. These distributing curves of scattering efficiency vs scattering angle are given in this paper, and it illuminates this direction character , which relates to X-ray＇ energy, atomic number Z of scattering element and strong scattering angle θ.
