Research Interests

Professor Safronova investigates relativistic and correlation effects in many-electron ions using relativistic many-body methods derived from Quantum Electrodynamics. These methods include second-order many-body perturbation theory. Applications are made to determine energies, radiative and non-radiative transition rates. These atomic data are important in modeling of K-, L-, and M-shells radiation spectra of heavy ions generated in electron beam ion trap experiments and in diagnostics of plasmas. Particular attention is given to He-, Li-, Be-, B-, Mg, Al-, Ne-, Na-, Ca-, Ni-, and Cu-like ions.

Prof. Safronova is a co-author of four monographs: ''Theory of Spectra of Multicharged Ions,'' ''Many-Body Problem and Atom Theory,'' ''Relativistic Theory of Atoms,'' and. ''Spectroscopy of Autoionization States of Atomic Systems'' published in Russian. She is a recipient of the Japan Society Promotion Science Fellowship from National Institute for Fusion Science in 1990, 1995, guest-professor National Institute for Fusion Science in 2000 and Japan Atomic Research Institute in 2001. She presently is a Principal Scientific Researcher at the Institute of Spectroscopy of Russian Academy of Science.
