For decades, nuclear physicists have faced a puzzling question: why do some atomic nuclei release far more low-energy gamma rays than expected?
A new study led by FRIB, with contributions from scientists at Lawrence Livermore National Laboratory, may finally provide the answer. Published in Nature, the research offers new insight into the inner workings of atomic nuclei and could have important implications for astrophysics, nuclear energy, national security, and nuclear forensics.
Starlust reports on new research exploring how stellar explosions create and spread chemical elements throughout the universe. Authors of one of the studies, from FRIB, examined a nuclear reaction that triggers X-ray bursts and clarified the role of the nickel-copper cycle, helping scientists better understand the processes that power these explosions.
Space.com reports on two recent studies that provide new insight into the nuclear reactions that power stellar explosions and create and distribute chemical elements throughout the universe.

A long-standing enigma in nuclear physics has puzzled scientists for decades: the phenomenon where certain atomic nuclei emit unexpectedly high quantities of low-energy gamma rays. A new study spearheaded by FRIB in collaboration with researchers from Lawrence Livermore National Laboratory sheds light on this mystery. The findings, published in Nature, deliver crucial insights into the structure of atomic nuclei and hold significant implications for fields such as astrophysics, nuclear energy, national security, and nuclear forensics.
A new theoretical study (“Dynamics of density fluctuations in atomic nuclei”) published in Physical Review Letters has identified rapid fluctuations in the density of atomic nuclei, offering a more detailed picture of how protons and neutrons move and interact.
Using advanced computational models, the researchers found that these fluctuations occur across different nuclei and appear to be a universal feature of nuclear dynamics. Unlike the slower changes captured by many existing models, the newly identified behavior arises from complex interactions between pairs of nucleons, providing new insight into the behavior of atomic nuclei and laying the groundwork for future studies of nuclear reactions, fission, and fusion.
The study was led by FRIB Theory Fellow Francesca Bonaiti, visiting assistant professor at FRIB, in collaboration with researchers at Oak Ridge National Laboratory and the University of Tennessee.
It has been a long-standing mystery in nuclear physics: why do the nuclei of some atoms emit more low-energy gamma rays than they should? The answer can be found in a new study from an international scientific team led by FRIB and including authors from Lawrence Livermore National Laboratory. Published in Nature, the work sheds light on the internal structure of atomic nuclei and has far-reaching implications for national security and astrophysics.
The University of Surrey reports on two studies that provide new experimental insight into nuclear reactions that occur during supernovae and X-ray bursts, helping scientists improve models of stellar explosions and element production. In one study, researchers working at FRIB measured a reaction that powers X-ray bursts with more than tenfold greater precision, clarifying the role of the nickel-copper cycle in shaping X-ray burst light curves.
