Experiments at FRIB enable discoveries

FRIB Experimental Nuclear Physics addresses all FRIB research themes by combining FRIB’s rare-isotope beams with state-of-the-art instrumentation, including lasers and precision traps, advanced gamma-ray spectrometers, a variety of particle detection systems, time projection chambers, and magnetic spectrometers and separators. Experiments at FRIB characterize the ground- and excited-state properties of rare isotopes not available elsewhere and explore their reactions and decays, often with implications for the understanding of the nucleosynthesis in the universe, physics beyond the standard model of particle physics, or their national benefit. FRIB Experimental Nuclear Physics is interdisciplinary and thrives through synergies arising from nuclear physicists, nuclear chemists, and atomic physicists joining forces in the common pursuit of discovery in nuclear science. 

Nuclear structure explores how protons and neutrons bind to form atomic nuclei, complex sub-atomic systems governed by quantum mechanics.

Explore nuclear structure

Nuclear astrophysics is a field that bridges nuclear science and astronomy, addressing fundamental questions about the universe, such as how chemical elements are formed and how their abundances change over time.
