How does spontaneous fission work?

Spontaneous Fission:

Spontaneous fission comprises a type of radioactive decay in which the nucleus of an atom breaks into 2 smaller nuclei and a single or more neutron. Frequently, spontaneous fission is most common in atoms having atomic numbers greater than 90. Excluding the heaviest isotopes, spontaneous fission is a sluggish process.

Answer and Explanation: 1

In 1941The Russian physicists, K.A. Petrzhak and G.N. Flerov observed spontaneous fission in uranium-238, and it is observed in numerous nuclear species with mass numbers of 230 or higher. Spontaneous fission incorporates a form of radioactive decay whereby specific volatile nuclei of heavier materials divide into two approximately equal fragments with lighter nuclei and release a considerable quantity of energy.
