HUN-REN Institute for Nuclear Research | Hungary

Károly Tőkési is a senior researcher at the HUN-REN Institute for Nuclear Research in Debrecen, Hungary, with an extensive scientific record in atomic, molecular, and nuclear-related physics. He has authored 350 documents indexed in Scopus, accumulating 4,801 citations with an h-index of 41, reflecting sustained impact across theoretical and applied physics communities. His research experience spans electron, positron, ion, and proton collisions with atoms and molecules, exotic atoms, ionization and charge-transfer cross sections, plasma-relevant atomic data, and spectroscopic studies of materials using reflection electron energy loss spectroscopy. He has contributed to both fundamental theory and applications relevant to fusion plasmas, exotic atomic systems, and materials characterization. His recent work includes publications in leading journals such as Physical Review Letters, Physical Review A, Nuclear Fusion, Plasma Physics and Controlled Fusion, Journal of Physics B, Atoms, and Scientific Reports, covering topics from orbital collapse in exotic atoms to detailed collision kinematics and cross-section databases. With a long-standing publication history and broad international collaborations, Károly Tőkési continues to advance precision understanding of particle–matter interactions and their role in modern physics research.
