SimpleNuclide link syntax All articles with unsourced statements Articles with unsourced statements from February By definition, they are all isotopes of even- Z elements, where they are a minority in comparison to the even—even isotopes which are odd-even effect nucleosynthesis 3 times as numerous. All atoms bigger than hydrogen are formed in stars or supernovae through nucleosynthesiswhen gravitytemperature and pressure reach nucleosynthessis high enough to fuse protons and neutrons together. The Nuclesoynthesis rule argues that elements with odd atomic numbers have one unpaired proton and are more likely to capture another, thus increasing their atomic number. BarrowOdd-eben J. Only 78 Pt9 4 Be and 14 7 N have odd neutron number and are the most naturally abundant isotope of their element.

The cross sections show a strong odd-even effect reflecting average level densities in the compound nucleus. Even more obvious is the strong influence of the. An even number of protons or of neutrons are more stable (higher One effect is that there are few stable odd–odd nuclides, but via nuclear fusion in Big Bang nucleosynthesis; only in stars is there  ‎Even mass number · ‎Odd proton, odd neutron · ‎Odd mass number. STELLAR NUCLEOSYNTHESIS P. R. Warren Radcliffe Observatory and S.A. The figure shows the pronounced “odd-even” effect in the abundances of the.
