The triple-alpha process is a set of nuclear fusion reactions by which three helium-4 nuclei (alpha particles) are transformed into carbon. Helium accumulates in the cores of stars as a result of the proton–proton chain reaction and the carbon–nitrogen–oxygen cycle. Nuclear fusion reaction of two … See more The triple-alpha process is ineffective at the pressures and temperatures early in the Big Bang. One consequence of this is that no significant amount of carbon was produced in the Big Bang. See more Ordinarily, the probability of the triple-alpha process is extremely small. However, the beryllium-8 ground state has almost exactly the energy of two alpha particles. In the second step, Be + He has almost exactly the energy of an excited state See more The triple-alpha steps are strongly dependent on the temperature and density of the stellar material. The power released by the reaction is approximately proportional to the temperature to the 40th power, and the density squared. In contrast, the See more With further increases of temperature and density, fusion processes produce nuclides only up to nickel-56 (which decays later to iron); heavier elements (those beyond Ni) are created mainly by neutron capture. The slow capture of neutrons, the s-process, produces about half … See more The triple-alpha process is highly dependent on carbon-12 and beryllium-8 having resonances with slightly more energy than See more Carbon is a necessary component of all known life. C, a stable isotope of carbon, is abundantly produced in stars due to three factors: 1. The decay lifetime of a Be nucleus is four orders of magnitude larger than the time for two He nuclei … See more WebDefine triple alpha process. triple alpha process synonyms, triple alpha process pronunciation, triple alpha process translation, English dictionary definition of triple alpha …
