本文提出了一种测量x射线吸收谱的新方法。它基于高分辨率光谱仪，可用于分析荧光光子能量，分辨率优于自然线宽。在Dy L（III）边缘的X射线吸收近边结构（XANES）的分辨率和详细的结构的显着改善。这项新技术揭示了使用传统XANES完全不可见的结构。
A novel method to measure x-ray-absorption spectra without the inner-shell lifetime broadening is presented. It is based on a high-resolution spectrometer which can be used to analyze the fluorescence photon energy with better resolution than the natural linewidth. The dramatic improvement in resolution and detailed structure for the x-ray-absorption near-edge structure (XANES) at the Dy L(III) edge is presented. This new technique reveals structure which is totally invisible using conventional XANES.
