Senior research scholar, Oleg Zatsarinny, and Klaus Bartschat, Ellis and Nelle Levitt Professor of Physics, published a Fast Track Communication in Journal of Physics B: Atomic, Molecular and Optical Physics, a part of IOPscience produced by the British Institute of Physics. The paper, entitled “Benchmark calculations of total cross sections for ionization-excitation of helium” proposes a solution to an over 30-year old problem and was judged by the referee as "an outstanding manuscript that takes the field to the next level.''

Zatsarinny earned his master’s degree from Moscow Institute of Physics and Technology in 1977 and his doctorate from Vilnius State University in 1985. He also earned a senior researcher degree from the Ukrainian Academy of Science in 2000. At Drake University, he teaches courses in computational physics, quantum mechanics, atomic physics, and electrodynamics. He has published over 100 peer-reviewed papers since coming to Drake in 2003.
