Spontaneous fission

  • abstract: Spontaneous fission (SF) is a form of radioactive decay that is found only in very heavy chemical elements. Because the nuclear binding energy of the elements reaches its maximum at an atomic mass number greater than about 58 atomic mass units (u), spontaneous breakdown into smaller nuclei and a few isolated nuclear particles becomes possible at heavier atomic mass units (amu).
