Nuclear fusion Definition from Science & Technology Dictionaries & Glossaries
General Chemistry Glossary
Compare with nuclear fission .Combination of two smaller nuclei to form a larger nucleus. The larger nucleus has higher binding energy per nucleon than the original nuclei, and fusion results in the release of energy.
ASTRONOMY UNBOUND
Process by which two atomic nuclei join to make a heavier one. This is the type of nuclear reaction that takes place in the centre of stars, for instance in the fusion of hydrogen into helium. It occurs with light elements , of mass less than iron, and it releases energy (i.e.it is an exothermic reaction) because the mass of the product is less than the sum of the two fusing particles; the mass defect (lost mass) is turned into energy according the famous E = m c2 equation.
Astronomy and Physics Terms by ExploreSpace.com
A nuclear process whereby several small nuclei are combined to make a larger one whose mass is slightly smaller than the sum of the small ones. The difference in mass is converted to energy by Einstein's famous equivalence E=mc2. This is the source of the Sun's energy and, ultimately, of (almost) all energy on Earth.
Nuclear fusion Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active or "main sequence" stars.
