Anharmonic effects, which describe deviations from the idealised harmonic oscillator model, play a pivotal role in refining extended X-ray absorption fine structure (EXAFS) analysis. By incorporating ...

Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a ...

This sharp jump in absorption is called the absorption edge. By tracking how X-ray absorption changes before, during and after this edge, researchers can watch the chemistry of a specific element ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...
