Resonant x-ray scattering (RXS) consists of elastic and inelastic processes. The former and latter are suitable for invesitigation of the ground and excited states, respectively. In this study, I have developed theories for analyzing the RXS spectra quantitatively, in particular, for the systems having complex ordering patterns. The inelastic process has been analyzed in the systems where multiple degrees of freedoms are active and those exhibit short range order, while the elastic process has been formulated in the systems possessing multipole order. The theories have been applied to some cuprates, iridate, and rare earth compounds and have succeeded in explaining the experimental results and predicting intriguing outcomes, which provide the progress in achieving the deeper understanding of the properties of such systems.

谐振X射线散射（RXS）由弹性和非弹性过程组成。前者和后者分别适用于地面和激发状态的发作。在这项研究中，我开发了用于定量分析RXS光谱的理论，特别是对于具有复杂排序模式的系统。在多个自由度活跃并且表现出短距离顺序的系统中，已经对非弹性过程进行了分析，而弹性过程已在具有多极顺序的系统中提出。这些理论已应用于某些铜料，屈服和稀土化合物，并成功地解释了实验结果并预测了有趣的结果，这为实现对这种系统的性质的深入了解提供了进步。
