| Summary: | Title screen Within the standard model of Big Bang Nucleosynthesis (BBN), there is a cosmological lithium problem, which consists in a substantial difference between calculated data on the abundances of the isotopes 6Li and 7Li and those that were found from observational astronomy. An attempt at measuring the cross section for the main 6Li production reaction 2H(4He, γ) 6Li induced by the interaction of 4He+ ions with deuterons at collision energies less than the lower boundary of the BBN energy range was made in the present study. Upper limits on the cross sections for the reaction in question were set. Режим доступа: по договору с организацией-держателем ресурса |
