When comparing nuclear fission at the venerable age of almost 84 years old with other quantum many-body systems (superconductivity, superfluidity, quantum Hall effect, fractional quantum Hall effect, magnetism, etc.) it is...
We have been conducting researches in many aspects of nuclear fission. Among them, a dynamical description of nuclear fission in terms of multidimensional Langevin equations has seen a reasonable success in explanation of the systematical and anomalous trends of distributions of fission fragment mass, total kinetic energy (TKE), and deformations. Especially, correlations of these observables...
The low energy fission in the actinide region is known to be mainly asymmetric, driven by structure effects of the nascent fragments [1]. Moreover, we know that there is a transition from asymmetric to symmetric splitting for Thorium isotopes. It was assumed that this latter split would be the main fission mode for lighter nuclei. Unexpectedly, an asymmetric split of the $^{180}$Hg nucleus was...
Prompt fission neutron energies play an important role in criticality, and measurements, calculations, and evaluations of them have been of interest, particularly for neutron-induced fission, for some time [1]. The Chi-Nu project at the Los Alamos Neutron Science Center has conducted a series of measurements of the prompt fission neutron spectra for neutron-induced fission, with the most...
Since its discovery, the fission process has been widely described in terms of a few collective coordinates often related to the shape of the nuclear density. As a matter of fact, theoretical approaches estimating a potential energy surface (PES) in a few-dimensional collective space are at the heart of our state-of-the art predictions of the fission yields and the spontaneous fission...
