![]() In the SF process, a fissioning nucleus undergoes quantum tunneling through a single or multiple potential barriers generated by the coherent motion of strongly interacting nucleons. The present scenario and the prospects of fission theory are described in a recent review. Therefore, for both basic science and applications, predictive modeling of SF observables is of utmost interest. However, measurements in actinide nuclei are restricted due to safety issues. In the application frontier, SF data are important to calibrate the nuclear material counting techniques relevant to power generation and international safeguards. Further, as suggested in a recent study, the precise estimation of fission yields is indispensable for a better understanding of the chemical evolution of r-process elements produced in binary neutron-star mergers. Specifically, distributions of fission-fragment yields from different fission modes (SF, beta-delayed fission, and neutron-induced fission) are essential components of the r-process abundances and, therefore, very accurate prediction of these yields is required to improve the r-process network calculations. In the case of nuclear astrophysics, SF strongly impacts the abundances of heavy elements in stars by participating in the r-process recycling mechanism. Moreover, in comparison to α-emission, SF is predicted to be the preferred decay mode for neutron-rich superheavy nuclei. This type of decay sequences are experimentally observed for isotopes of Fl and Ts. ![]() Although superheavy nuclei predominantly decay via α-emission at the beginning of a decay chain, SF leads to terminate the chain. Particularly, the stability of very heavy and superheavy nuclei strongly depends on the SF probability. Nuclear spontaneous fission (SF) is a unique decay mechanism that has crucial applications in both basic and applied sciences.
