Theory of nuclear fission
Webb22 feb. 2024 · Quantum shell effects stabilising fission fragments with various shapes have been invoked as a factor determining the distribution of nucleons between the fragments at scission. Shell effects also induce asymmetric shapes in the nucleus on its way to fission well before the final fragments are (pre)formed. These shell effects are … Webb1 juli 2024 · Atomic nuclei are quantum many-body systems of protons and neutrons held together by strong nuclear forces.

WebbNuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei.The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.. Nuclear fission of heavy elements was discovered on Monday 19 December 1938 in Berlin, by …
WebbThe basic tenets of this method, including some well-known tools such as the Hartree-Fock-Bogoliubov (HFB) theory, effective two-body nuclear potentials such as the Skyrme and Gogny force, finite-temperature extensions and beyond mean-field corrections, are presented succinctly. Nuclear fission can occur without neutron bombardment as a type of radioactive decay. This type of fission (called spontaneous fission) is rare except in a few heavy isotopes. In engineered nuclear devices, essentially all nuclear fission occurs as a "nuclear reaction" — a bombardment-driven process that results from the collision of tw…
WebbSince then, he has been working on theories and models of nuclear reaction mechanisms, nuclear fission, nuclear data evaluations, uncertainty quantification and Bayesian statistics. He has authored more than 150 publications in refereed journals and international conference proceedings. WebbIn connection with nuclear fission we study the division of an idealized charged drop, using a simplified version of the liquid-drop model. The degrees of freedom essential to a discussion of the division of a charged drop and the separation of the fragments to infinity are taken into account: a fragment-separation coordinate, a mass-asymmetry …

Webb15 apr. 2024 · Nuclear fission represents the ultimate test for microscopic theories of nuclear structure and reactions. Fission is a large-amplitude, time-dependent phenomenon taking place in a self-bound, strongly interacting many-body system.
