X-Ray Database

The development of physical-chemistry interactions of low-energy X-rays within matter (i.e., photoabsorption and coherent scattering) for photon energies above the absorption threshold. These tables compile available experimental measurements and theoretical calculations. For many elements, there is little or no published data, and in such cases, it was necessary to rely on theoretical calculations and Z-dependent interpolations. To improve accuracy in the future, considerably more experimental measurements are needed.

物质对低能X射线的相互作用，即光电吸收和相干散射现象，已在其吸收阈值区域之外的能量范围内进行了详细描述。这些表格基于对现有实验测量和理论计算的汇编。对于许多元素，现有的公开发表数据寥寥无几，在缺乏此类数据的情况下，不得不依赖于理论计算和对原子序数Z跨度的插值。为了显著提高未来的精度，需要开展大量额外的实验测量。
