thermonuclear reaction
fusion of two light atomic nuclei into a single heavier nucleus by a collision of the two interacting particles at extremely high temperatures, with the consequent release of a relatively large amount of energy. Chains of thermonuclear reactions, such as the proton-proton cycle (q.v.) and the carbon cycle (q.v.), account for the energy radiated from the Sun and most other stars. In an uncontrolled state, this type of nuclear reaction is responsible for the destructive force of thermonuclear bombs. See also nuclear fusion.
