Spontaneous fission
Spontaneous fission
(SF) is a form of
radioactive decay
that is found only in very heavy
chemical elements
. The
nuclear binding energy
of the elements reaches its maximum at an
atomic mass number
of about 58; spontaneous breakdown into smaller nuclei and a few isolated
nuclear particles
becomes possible at greater
atomic mass numbers
.
