fusion
subject			fact

fusion	has antonym fission
	produces energy
	has product
	has reaction probability
	has catalyst
	has reactant
	has minimum temperature
	has definition In nuclear physics, the combining of the atomic nuclei of lighter elements to form nuclei of a heavier element. Such a process involving the atomic nuclei of elements lighter than iron is accompanied by the emission of energy; for fusion of heavier elements, energy must be supplied. The process is thought to contribute to the condensation of stars from interstellar gas and dust. See also nuclear fusion.
	has definition Interaction in which nucleons are forged together, creating new atomic nuclei and releasing energy. Fusion powers hydrogen bombs.
	has definition Process by which the Sun (and other stars) radiates energy. The nucleus of an atom fuses with the nuclei of other atoms to form new, heavier atoms at the same time releasing large amounts of energy. In the Sun, hydrogen atoms are converted into helium by this process, with carbon and nitrogen as intermediates. Cooler stars undergo the proton-proton cycle with a similar result.
	is a kind of nuclear process
physical process	has domain physics

Kinds of fusion :

• endothermic fusion process (1 kind, 4 facts) - a fusion process which requires energy
• exothermic fusion process (16 kinds, 114 facts) - A fusion reaction which linerates energy.
• nucleosynthesis (4 kinds, 15 facts) - The production of heavy nuclei from the fusion of lighter ones.
