The Theory of Inelastic Scattering and Absorption of X-rays
This comprehensive, self-contained guide to X-ray spectroscopy will equip you with everything you need to begin extracting the maximum amount of information available from X-ray spectra. Key topics such as the interaction between X-rays and matter, the basic theory of spectroscopy, and selection and sum rules, are introduced from the ground up, providing a solid theoretical grounding. The book also introduces core underlying concepts such as atomic structure, solid-state effects, the fundamentals of tensor algebra and group theory, many-body interactions, scattering theory, and response functions, placing spectroscopy within a broader conceptual framework, and encouraging a deep understanding of this essential theoretical background. Suitable for graduate students, researchers, materials scientists and optical engineers, this is the definitive guide to the theory behind this powerful and widely used technique.

Measurements of x-ray magnetic circular dichroism (XMCD) and x-ray absorption near-edge structure (XANES) spectroscopy at the Pu M4,5 edges of the ferromagnet PuSb are reported. Using bulk magnetization measurements and a sum rule analysis of the XMCD spectra, we determine the individual orbital [μL =2.8(1)μB/Pu] and spin moments [μS = −2.0(1)μB/Pu] of the Pu 5f electrons. Atomic multiplet calculations of the XMCD and XANES spectra reproduce well the experimental data and are consistent with the experimental
Xclaim: a graphical interface for the calculation of core-hole spectroscopies
Xclaim (X-ray core level atomic multiplets) is a graphical interface for the calculation of core-hole spec-troscopy and ground state properties within a charge-transfer multiplet model taking into account amany-body Hamiltonian with Coulomb, spin–orbit, crystal-field, and hybridization interactions. UsingCoulomb and spin–orbit parameters calculated in the Hartree–Fock limit and ligand field parameters(crystal-field, hybridization and charge-transfer energy) the program calculates X-ray absorption spec-troscopy (XAS), X-ray photoemission spectroscopy (XPS), photoemission spectroscopy (PES) and inversephotoemission (IPES). The program runs on Linux, Windows and MacOS platforms.
