Nuclear mass versus the mass of free nucleons. Two concepts are central to both nuclear fission and fusion: First, the mass of a nucleus is less than the sum of the masses the nucleons would have if they were free. This is called the mass defect.

WebNuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays) and releases a large amount of energy. In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process.

Web8 apr. 2024 · There are other modes of cluster decay, including spontaneous fission, yielding products heavier than an $\alpha$, but the $\alpha$-emission is the most energetically preferred.
