Webb16 maj 2024 · Nuclear fission process provides a suitable platform to study large-amplitude collective dynamics in nuclei, and the pertaining theoretical model can reveal the nature of the underlying interactions by correlating them with fission observables. Two primary measurable quantities in fission decay are the fission yields and the decay half … 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.
