Gamma Emission andInternal Conversion

Gamma emission is not a transformation of one element into another but rather a de- excitation process. After a nucles undergoe alpha or beta decay, it often consult in an excited energy state.

For superheavy elements, the competition between alpha decay and spontanous fission is especially critical.
