Jerry Seidler: What is X-ray Raman Scattering, and What Did Raman Have to Do With It?
X-ray Raman Scattering (XRS, often also called nonresonant inelastic x-ray scattering), is a hard x-ray alternative to soft x-ray NEXAFS. I'll review the basic physics, including the role of momentum transfer to tune selection rules. And I'll explain Raman's involvement, or lack thereof.

Simo Huotari: X-ray Raman spectroscopy: glimpse of the state of the art for samples in complex environments
In this lecture I will continue where the previous lecture ends and talk about some examples of how XRS is used to study materials under high pressure and chemical reactions.

Evan Jahrman Core-to-core X-ray Emission Spectroscopy: Pitfalls and Advantages for Lab-based and Synchrotron Users
Core-to-core X-ray emission spectroscopy (CTC-XES) has not only provided key insights into atomic physics but is extremely well positioned to serve as a major analytical technique for several materials systems in the coming decades. Moreover, CTC-XES frequently serves as an enabling phenomenon for more exotic varieties of synchrotron-based XAFS. I will cover several applications of […]
