Georg Bollen

Georg Bollen is a University Distinguished Professor in the Department of Physics & Astronomy at Michigan State University (College of Natural Science). His research focuses on nuclear and atomic physics, particularly on high-precision mass measurements of exotic atomic nuclei far from stability and laser spectroscopy for probing nuclear size and shape.

• Ph.D., Mainz University (1989)

He leads projects at the National Superconducting Cyclotron Laboratory (NSCL), utilizing the Low Energy Beam and Ion Trap (LEBIT) facility for mass measurements with accuracies below 10^-8 (9.4 Tesla magnetic field). His work also involves developing advanced techniques for rare isotope beam manipulation, including gas-stopping, cooling, bunching, and charge breeding for the NSCL re-accelerator project. These studies test nuclear models, reveal element synthesis mechanisms in the universe, and probe fundamental symmetries.

His recent publications highlight innovations in ion trapping (e.g., radiofrequency carpets), double-beta decay experiments, and applications of the rp-process. All articles emphasize nuclear physics, rare isotopes, and precision instrumentation.

• University Distinguished Professor

Georg Bollen's group contributes to rare isotope research at NSCL, integrating high-precision mass spectrometry and laser spectroscopy. They collaborate on building facilities like the charge breeder for re-acceleration, enabling unique experimental opportunities. The group's work intersects experimental nuclear physics, astrophysics, and particle physics to explore fundamental nuclear properties.
