Predictive capabilities for the behavior of nuclear systems driven by neutron-induced fission rely heavily on an accurate understanding of input nuclear data. The energy spectrum of neutrons promptly emitted from neutron-induced fission, i.e., the prompt fission neutron spectrum (PFNS), is of fundamental importance for these systems. Over the last decade the Chi-Nu experimental team at Los...
The experimental search for the existence of a tetra neutron state has a long history, and the situation remained unclear until recently, and a possible explanation of our experimental finding is still open. On the theoretical side, large efforts have been undertaken as well recently, with results and predictions scattering over wide range in energy, including the prediction for the...
The Beta-Delayed Neutrons at RIKEN (BRIKEN) collaboration has measured beta-delayed neutron emission probabilities and decay half-lives for some of the most unstable isotopes accessible to experiments. The results provide a wealth of information on the nuclear structure and decay properties of neutron-rich isotopes, and nuclear data critically needed for astrophysics models. The measurements...
