Nuclear fusion is a reaction in which two or more atomic nuclei (for example, nuclei of hydrogen isotopes deuterium and tritium), combine to form one or more atomic nuclei and neutrons. The difference in mass between the reactants and products is manifested as either the release or absorption of energy.

2025年1月23日 · Nuclear fusion, process by which nuclear reactions between light elements form heavier elements. In cases where interacting nuclei belong to elements with low atomic numbers, substantial amounts of energy are released.

Fusion reactions power the Sun and other stars. In fusion, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

2022年3月31日 · Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. Fusion reactions take place in a state of matter called plasma — a hot, charged gas made of positive ions and free-moving electrons with unique properties distinct from solids, liquids or gases.

2023年4月30日 · Nuclear fusion is a type of nuclear reaction where two or more atomic nuclei combine and form one or more heavier nuclei. The process of fusion forms many of the elements of the periodic table , plus it offers an opportunity for limitless energy production.

Nuclear fusion is a nuclear reaction that combines two or more small atoms to form a large atom. It does not occur naturally. The universe is full of instances of nuclear fusion reactions.

The most promising of the hydrogen fusion reactions which make up the deuterium cycle is the fusion of deuterium and tritium. The reaction yields 17.6 MeV of energy but to achieve fusion one must penetrate the coulomb barrier with the aid of tunneling, requiring very high temperatures .

Energy obtained from fusion and fission reactions is based on differences in the nuclear binding energy. The mass of the products of a fusion reaction is smaller than the mass of its reactants. The difference or "missing mass" is converted into energy in …
