Nigel Orr received his Ph.D. in nuclear physics in 1989 at the Australian National University. He completed a postdoc at the Large Heavy Ion National Accelerator (GANIL) in France and, later, at the National Superconducting Cyclotron Laboratory in the U.S. Since 1993, he has been a Research Scientist with the French CNRS. He is currently “Directeur de Recherche” (Senior Scientist) at LPC-Caen. His main research interests are in the structure of very neutron-rich nuclei and experiments with radioactive beams at the RIBF-RIKEN (Japan), TRIUMF (Canada), and GANIL (France) facilities.


Can Four Neutrons Tango?

Evidence that the four-neutron system known as the tetraneutron exists as a resonance has been uncovered in an experiment at the RIKEN Radioactive Ion Beam Factory. Read More »
