The final piece of a longstanding adventure started in 2014 with an experiment led by Irfu and RIKEN Nishina Center has been set with the publication of a paper containing the comparative study of dineutron correlation in 11Li, 14Be and 17B [1]. This paper published in Phys. Lett.
Pairing is ubiquitous in physics. From superconductivity to quantum shell structure, coupling particles into pairs is one of nature's preferred ways to lower the energy of a system.
An international collaboration led by the institutes of CEA-IRFU and of RIKEN (Japan) demonstrates, for the first time, the exceptional stability of the very-neutron rich nickel-78 nucleus and its doubly-magic character.
An international team has performed the first spectroscopy of the very neutron-rich isotopes 98,100 Kr. The collaboration, led by scientists from the CEA Irfu and RIKEN (Japan) included several European groups and physicists from IPN-Orsay.
The "exotic" nuclei pose the challenge of a universal description of the nuclear structure and raise the question of the evolution of the shell structure. An IRFU team has developed the Magic Number Off Stability (MINOS) project to answer these questions.
