Big Bang ruled out as origin of lithium-6 – Physics World

WebThose stars have [Fe/H] values no larger than −1.5 and sometimes as low as −3.5. Called metallicity, [Fe/H] indicates the overall abundance of elements beyond hydrogen and helium, up to and including iron. Also, r-I and r-II stars presumably formed early in cosmic history, whereas the solar system is a relatively youthful 4.6 billion years old. Web2 sep. 2014 · The production of lithium-6 by BBN should be dominated by one nuclear reaction, namely the collision and subsequent fusion of deuterium (hydrogen-2) with helium-4 to create lithium-6 and a gamma ray. Bemmerer and colleagues have now used the 400 kV accelerator at LUNA to study this interaction at two collision energies that would have … grammy tribute to beach boysHelium has a valence of zero and is chemically unreactive under all normal conditions. It is an electrical insulator unless ionized. As with the other noble gases, helium has metastable energy levels that allow it to remain ionized in an electrical discharge with a voltage below its ionization potential. Helium can form unstable compounds, known as excimers, with tungsten, iodine, fluorine, sulfur, and phosphorus when it is subjected to a glow discharge, to electron bombardm… china tea club lyneham
