Nuclear Systematics: I. Solar Abundance of the Elements
Nuclear systematics and the abundance of elements and isotopes in meteorites, in planets, in the solar photosphere, in the solar wind, and in solar flares are used to estimate the abundance of elements in the Sun. The results indicate that 56Fe, the decay product of doubly-magic 56Ni, is the Sun's most abundant nuclide. The next most abundant nuclide is the doubly-magic 16O. The most abundant elements - Fe, Ni, O, Si, S, Mg, and Ca - are the even-Z elements that Harkins1 found to comprise ~99% of ordinary meteorites. The least abundant elements have loosely bound nucleons (Li, Be and B) further confirming the proposed link1 between abundance and nuclear structure, with one conspicuous and important exception. Diffusion enriches light-weight nuclides at the solar surface, hiding the link of abundance to nuclear stability beneath the Sun's H-rich exterior.
