单晶具有高达的原子电场，其对应于的磁场。这些场可以用于将X射线转换成类似于X射线衍射的轴状粒子（ALP）。本文基于X射线衍射的达尔文动力学理论，首次对晶体中的劳厄转换进行了理论计算。计算结果表明，劳厄转换比布拉格转换具有更长的相互作用长度，并且通过调节X射线的入射角，可以实现keV范围内的ALP共振转换.质量高达的ALP可以通过同步加速器X射线设施上的光穿透墙壁（LSW）实验来搜索。
Single crystals have high atomic electric fields as much as, which correspond to magnetic fields of. These fields can be utilized to convert x-rays into axionlike particles (ALPs) coherently similar to x-ray diffraction. In this paper, we perform the first theoretical calculation of the Laue-case conversion in crystals based on the Darwin dynamical theory of x-ray diffraction. The calculation shows that the Laue-case conversion has longer interaction length than the Bragg case, and that ALPs in the keV range can be resonantly converted by tuning an incident angle of x-rays. ALPs with mass up tocan be searched by light-shining-through-a-wall (LSW) experiments at synchrotron x-ray facilities.
