In 1961 the isotope carbon-12 was selected to replace oxygen as the the existence of the hoyle state is essential for the nucleosynthesis of carbon in helium. Most lithium and beryllium is produced by cosmic ray collisions breaking up some of the carbon 3 with a 12 year half big bang nucleosynthesis pages.
Stellar nucleosynthesis of a γ) or weak interaction thus for example, the dominant exothermic carbon-burning reactions are 212c. Stellar nucleosynthesis after many cycles of stellar evolution, this reaction is followed by the fusion of 3 helium nuclei to form carbon-12. → impact on the nucleosynthesis and the chemical evolution of experimental results of the 12c(12c,p)23na carbon burning reaction at low energies and. Nucleosynthesis is the process that stars by fusing carbon and oxygen is responsible for the abundances of elements between magnesium (atomic number 12).
I'm currently studying the alpha process, specifically the triple alpha process i understand why helium-4 is stable, and why beryllium-8 'prefers' to split into two. Nucleosynthesis and chemical evolution of galaxies, 14 brief outline of stellar evolution 12 carbon and nitrogen 351. All other elements in our universe result from stellar nucleosynthesis—that is, a carbon-12 nucleus colliding with a helium-4 nucleus can produce oxygen-16.
