RIKEN Nishina Center for Accelerator-Based Science is a research center for nuclear physics. The center has two main divisions: an experimental division where scientists conduct accelerator research and a theoretical one where scientists perform fundamental research. Our accelerators can utilize many different types of nuclei, providing precious opportunities for researchers to study the structure and properties of nuclei in exquisite detail. The center is unique in the close collaboration enjoyed by theoretical and experimental scientists in exploring the mysteries of nuclei using the world’s leading accelerator complex. The center focuses its support on sharing accelerator time with researchers around the world, promoting the center as a global research center.
Major step forward in theoretical description of two key properties of hot nuclei
In work published in Physical Review Letters, researchers from the RIKEN Nishina Center for Accelerator-Based Science and two universities in Vietnam—Duy Tan University and University of Khanh Hoa—have made a major breakthrough by proposing, for the first time, a unified and consistent microscopic approach capable of describing simultaneously two important quantities for understanding the statistical properties of nuclei—the nuclear level density and the emission probability of gamma-rays from hot nuclei—which play essential roles in stellar nucleosynthesis.
For the violent r-process, the devil’s in the details
Using RIKEN’s Radioactive Isotope Beam Factory—one of the world’s most powerful devices for the creation of exotic atomic nuclei—scientists from RIKEN have, with international collaborators, made precise measurements of the half-lives of 110 nuclei, 40 of which had never been measured before.
Supernova mystery unraveled
One of the big mysteries of our universe, how stellar explosions called supernovas occur, is being unraveled thanks to a new telescope developed by NASA/JPL-Caltech with contributions from RIKEN scientists.
‘Magic number‘ disappear and expand area of nuclear deformation
The magic numbers 20 and 28 disappear from all neutron-rich magnesium isotopes, thereby establishing a new, larger area of nuclear deformation in the nuclear chart.
Evidence for a new nuclear ‘magic number‘
Researchers have come one step closer to understanding unstable atomic nuclei. A team of researchers from RIKEN, the University of Tokyo and other institutions in Japan and Italy has provided evidence for a new nuclear magic number in the unstable, radioactive calcium isotope 54Ca. In a study published today in the journal Nature, they show that 54Ca is the first known nucleus with 34 neutrons (N) where N = 34 is a magic number.

Hiroshi Imao awarded ACFA/IPAC'13 Accelerator Prize
It was announced that Dr. Hiroshi Imao of Accelerator R&D team will be awarded the "Accelerator Prize (c)" by Asian Committee for Future Accelerators (ACFA).
Search for element 113 concluded at last
After many years of painstaking work, Dr. Kosuke Morita (RIKEN Nishina Center) and his team prove third time's a charm.
The groundbreaking result, reported in the Journal of Physical Society of Japan, sets the stage for Japan to claim naming rights for the element.
Researchers have calculated the value of the anomalous magnetic moment of the electron and muon to the most precise degree known to physics.
Dr. Makiko NIO (RIKEN Nishina center) and collaborators calculated electron's magnetic moment to unprecedented precision as a level of one part in 1.5 billion.
Euroball-RIKEN Cluster Array (EURICA) Project unveiled
A new project with the goal of performing γ-ray nuclei spectroscopy has been launched bringing together the world's largest γ-ray detectors (Euroball germanium Cluster-detectors) and the Radioactive Isotope Beam Factory (RIBF) at the RIKEN Nishina Center. The new project, named EURICA (Euroball-RIKEN Cluster Array), was commissioned on 28th March, 2012.
