A new approach for nuclear forensics investigations of uranium dioxide: Application of laboratory-based photoelectron spectroscopy with hard and Soft X-ray sources

Applied Surface Science Advances
Nuclear Forensic investigations rely on the analysis of the chemical and physical properties of nuclear materials. X-ray photoelectron spectroscopy (XPS) is a powerful tool that supports material assessment, typically analyzing the top few nanometers of ...
