%X X-ray-induced damage is one of the key topics in radiation chemistry. Substantialdamage is attributed to low-energy electrons and radicals emergingfrom direct inner-shell photoionization or produced by subsequent processes.We apply multi-electron coincidence spectroscopy to X-ray-irradiated aqueoussolutions of inorganic ions to investigate the production of low-energyelectrons (LEEs) in a predicted cascade of intermolecular charge- and energytransferprocesses, namely electron-transfer-mediated decay (ETMD) andinteratomic/intermolecular Coulombic decay (ICD). An advanced coincidencetechnique allows us to identify several LEE-producing steps during the decayof 1s vacancies in solvated Mg<sup>2+</sup> ions, which escaped observation in previousnon-coincident experiments. We provide strong evidence for the predictedrecovering of the ion’s initial state. In natural environments the recovering ofthe ion’s initial state is expected to cause inorganic ions to be radiationdamagehot spots, repeatedly producing destructive particles under continuousirradiation.
