The “Beta-Delayed Neutrons at RIKEN” project (BRIKEN): conquering the most exotic beta-delayed neutron-emitters
Rights accessOpen Access
Among the main missions of modern radioactive isotope facilities is the exploration of properties of yet unknown isotopes on the neutron-rich side of the chart of nuclides. However, going more neutron-rich also means that the neutron separation energy decreases until it reaches the dripline at Sn = 0 MeV. If the neutron separation energy gets lower than the ß-decay energy window (Qß value), a new decay mechanism can occur: the emission of neutrons after ß-decay. These “ß-delayed neutron” (ßn) emitters play a crucial role in nuclear structure, nuclear astrophysics, and for nuclear reactor applications.
