Related to Fusion reaction: Fission reaction
the formation of more complex atomic nuclei from less complex nuclei with release of energy, as in the formation of helium nuclei from hydrogen nuclei (hydrogen fusion).
Joining of the nucleus of small atoms to form larger atoms. It occurs when temperatures reach millions of degrees. An example is the nuclear reaction joining hydrogen together to form helium and resulting in the significant release of energy.
