本文简要概述了先进的X射线光谱技术的应用，利用共振非弹性X射线散射（RIXS）在硬和软X射线范围内，最近已成为研究锕系元素的电子结构。在这里，我们专注于高能量分辨率的X射线吸收近边结构（XANES）和核心到核心和核心到价的RIXS光谱在铀化合物的U L和M边缘。使用一些理论方法，如安德森杂质模型，密度泛函理论在局域密度近似与附加库仑相互作用（LDA + U），和全多重散射（FEFF）和从头算有限差分法近边结构（FDMNES）代码的光谱特征进行了分析。与所提出的结果，实验技术和理论方法的能力和局限性进行了讨论。(C)2014爱思唯尔有限公司版权所有。
This paper provides a brief overview of applications of advanced X-ray spectroscopic techniques that take advantage of the resonant inelastic X-ray scattering (RIXS) in the hard and tender X-ray range and have recently become available for studying the electronic structure of actinides. We focus here on the high-energy-resolution X-ray absorption near edge structure (XANES) and core-to-core and core-to-valence RIXS spectroscopies at the U L and M edges of uranium compounds. The spectral features are analyzed using a number of theoretical methods, such as the Anderson impurity model, density functional theory in the local density approximation with an added Coulomb interaction (LDA + U), and full multiple scattering (FEFF) and ab initio finite difference method near-edge structure (FDMNES) codes. In connection with presented results, the capabilities and limitations of the experimental techniques and theoretical methods are discussed. (C) 2014 Elsevier B.V. All rights reserved.
