FRIB researchers participated in an experiment at Argonne National Laboratory using the new Argonne Tandem Hall Laser Beamline for Atom and Ion Spectroscopy (ATLANTIS) to make precise measurements of unstable ruthenium isotopes, helping test modern models that describe how atomic nuclei behave. The results show strong agreement between measurements and theoretical predictions, increasing confidence in these models for understanding rare nuclei and the processes that shape matter in the universe.

Michigan State University has selected Carl Craig, one of Detroit’s most influential electronic music pioneers, as its 2026 MSUFCU Arts Power Up artist-in-residence, marking a rare crossover between techno culture, scientific research, and academic inquiry. Running from mid-January through April 2026, the residency places Craig in direct collaboration with researchers at FRIB, where Craig will explore how sound, technology, and experimental research environments can inform new creative and conceptual frameworks.
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams and current postdoctoral fellow at the University of Regina in Canada, the study presents the first rare isotope beam measurement of proton capture on arsenic-73 to produce selenium-74, providing new constraints on how the lightest p-nucleus is formed and destroyed in the cosmos. The team published its results in Physical Review Letters “Constraining the Synthesis of the Lightest 𝑝 Nucleus 74Se”.

Michigan State University has selected internationally renowned Detroit DJ, producer, and techno innovator Carl Craig as a MSUFCU Arts Power Up artist-in-residence, a program that brings visionary artists to campus to explore the intersections of creativity, research, and technology. Widely regarded as one of the most influential figures in electronic music, Craig will be in residence from mid-January through April 2026, working in close collaboration with researchers at FRIB.
A research team at FRIB is the first ever to observe a beta-delayed neutron emission from fluorine-25, a rare, unstable nuclide. Using the FRIB Decay Station Initiator (FDSi), the team found contradictions in prior experimental findings. The results led to a new line of inquiry into how particles in exotic, unstable isotopes remain bound under extreme conditions.

Researchers at FRIB have achieved a significant milestone in nuclear physics by detecting beta-delayed neutron emission from fluorine-25, an elusive and unstable nuclide. This groundbreaking discovery, made possible through the utilization of the FRIB Decay Station Initiator (FDSi), has unveiled new insights into the behavior of exotic isotopes under extreme conditions.
Physicists from institutions including FRIB used state-of-the-art ab-initio nuclear theory to show that several neutron-rich magnesium isotopes near neutron number 20 exhibit both normal and deformed shapes at low energy—evidence of shape coexistence and a breakdown of the traditional “magic” shell closure at . The work helps resolve longstanding questions about this region of the nuclear chart and identifies isotopes whose structures can be tested with modern rare-isotope facilities.
Physicists at the Massachusetts Institute of Technology (MIT), in collaboration with institutions including the European Organization for Nuclear Research (CERN), have developed a new molecule-based technique that uses the atom’s own electrons as “messengers” to probe its nucleus, bypassing the need for large-scale particle accelerators. In the experiment, electrons bound in a radium-fluoride molecule briefly entered the radium nucleus and returned with subtle shifts in energy that reveal internal nuclear structure. Among the study’s co-authors is Shane Wilkins, who now works at FRIB.
Researchers used collinear laser spectroscopy to make precise measurements of nuclear charge radii across a long series of tin isotopes, revealing how nuclear structure evolves as neutrons are added. The results show clear trends and reveal pronounced odd–even staggering near neutron shell closures, providing important tests for models that describe how protons and neutrons interact inside the nucleus. This type of high-precision nuclear-structure information helps guide experiments at FRIB, where scientists study rare isotopes to better understand the forces that govern nuclear matter.
