Measurement of the most exotic neutron emitters at BRIKEN:
The BRIKEN (Beta-delayed neutron measurements at RIKEN for nuclear structure, astrophysics, and applications) project started in 2016 at the RIKEN Nishina Center in Japan. As reported in the Journal of Instrumentation (2017) the ambitious goal of the collaboration is to design the most efficient neutron detector array for the measurement of the most exotic nuclei that can be produced today. With TRIUMF research collaboration, so far 268 nuclei have been measured, and for 180 of them the neutron branching ratio and for 60 the decay half-life has been measured for the first time. The neutron-branching ratio of the doubly-magic isotope nickel-78 has been measured for the first time, and will help to pinpoint theoretical predictions of neutron-magic nuclei.
