nuclear reactions

Reactions involving changes in atomic nuclei. Nuclear reactions include nuclear fusion and fission and transformations of nuclei by bombardment with particles or photons. The energy released by nuclear reactions is equivalent to a decrease in mass according to Einstein's equation (E = mc 2) and appears in the form of kinetic energy of the particles or photons of electromagnetic radiation.
