A new x-ray technique to unravel electronic properties of actinide compounds

A new research demonstrates a direct and selective way to investigate 5f electrons in actinide compounds as well as their interaction with other valence electrons

Actinides are a series of chemical elements that form the basis of nuclear fission technology, finding applications in strategic areas such as power generation, space exploration, diagnostics and medical treatments, and also in some special glass. Thorium (Th) and Uranium (U) are the most abundant actinides in the Earth’s crust.
